Rams 2026 Defense Takes Crushing Blow After Superstar Injury

The Los Angeles Rams spent the offseason assembling a defense that looked capable of becoming one of the NFL's most intimidating units in 2026. Just one game into the season, however, that vision has already encountered its first major obstacle. Superstar pass rusher Myles Garrett is expected to undergo arthroscopic knee surgery and be placed on injured reserve, sidelining one of the biggest additions to Los Angeles' championship-caliber roster for at least four games. For a Rams team trying to recover from an ugly season-opening loss, the injury immediately raises questions about the defense both now and later in the season.

Garrett's absence could hardly come at a worse time for Los Angeles. The Rams failed to record a sack in their 27-7 loss to the San Francisco 49ers in Melbourne, and their supposedly dominant defensive front struggled to consistently affect Brock Purdy. That disappointing performance was one of several moments that turned a highly anticipated opener into an early wake-up call for a team with Super Bowl expectations. Now the Rams must figure out how to generate pressure without the player they acquired specifically to transform their pass rush.

How Long Will Myles Garrett Be Out?

Garrett is expected to miss at least the next four games after undergoing arthroscopic surgery on his knee and being placed on injured reserve. Under NFL injured-reserve rules, that means Los Angeles will be without him against the New York Giants, Denver Broncos, Philadelphia Eagles, and Buffalo Bills. The earliest Garrett could become eligible to return is Week Six against the Arizona Cardinals. His actual return date will depend on how his knee responds to surgery and rehabilitation, making his recovery one of the biggest Rams storylines to monitor over the next month.

The injury did not suddenly appear after the opener. Garrett missed much of training camp while dealing with knee swelling, although the Rams ultimately cleared him to play against San Francisco without a final injury designation. He played 40 of Los Angeles' 65 defensive snaps but failed to record a tackle or quarterback hit during an extremely quiet Rams debut. Garrett acknowledged afterward that his health affected him during the game and described the performance as the worst version of himself he had put on the field.

That context makes the decision to undergo surgery more understandable, but also more concerning. Los Angeles clearly hoped Garrett could manage the knee problem without requiring an extended absence, especially after investing so heavily to acquire him during the offseason. Instead, the Rams are now shutting him down early to solve the problem rather than letting it linger throughout the season. If the procedure allows Garrett to return closer to full strength later in 2026, the short-term pain could ultimately protect Los Angeles from a much bigger long-term problem.

Why This Injury Changes the Rams Defense

The Rams did not acquire Garrett merely to add another productive defensive player. They brought him to Los Angeles to become the centerpiece of a potentially overwhelming pass rush and give opposing offenses a problem they could not easily scheme around. Garrett entered 2026 after recording an NFL record 23 sacks the previous season, giving Los Angeles one of the most accomplished edge defenders in football. Removing that kind of player from the lineup changes how every other member of the defensive front will be defended.

Opposing offenses no longer have to devote the same amount of protection toward Garrett's side of the formation. That could mean additional attention for Byron Young, Kobie Turner, Braden Fiske, and eventually Aaron Donald when the Rams' defensive legend returns to the lineup. Los Angeles still possesses considerable talent, but the entire concept behind this defense was to create pressure from several directions. Losing arguably the most dangerous individual pass rusher in that equation makes the challenge considerably harder.

The Week One performance demonstrated why that matters. Los Angeles hit Purdy only twice and failed to bring him down for a sack, giving the 49ers quarterback enough time to throw three touchdown passes. San Francisco also rushed for 174 yards, preventing the Rams from consistently creating obvious passing situations where their defensive front could attack. If Los Angeles cannot generate pressure without blitzing heavily, the absence of Garrett could eventually create problems for the secondary as well.

Aaron Donald Suddenly Becomes Even More Important

There was already enormous anticipation surrounding Aaron Donald's return to Los Angeles, but Garrett's injury has dramatically changed the circumstances. Donald initially returned from retirement with the possibility of playing alongside Garrett on a loaded defensive front. Instead, his first games back could come with Garrett watching from the sideline. That transforms Donald from an extraordinary addition to a player the Rams may immediately need to stabilize their defense.

Donald did not travel to Australia for Week One as Los Angeles continued to carefully manage his return after two seasons away from football. The Rams have remained patient with their defensive legend, understanding that rushing him onto the field could create unnecessary risk after such a long absence. His potential 2026 debut against the Giants now carries even more significance because the Rams desperately need another player capable of commanding double teams and disrupting the pocket. Even if Donald initially operates on a limited snap count, his presence could completely change how opponents approach the Los Angeles defensive front.

The Rams also cannot expect Donald to immediately become the same player who dominated the NFL before retiring. He is 35 years old and has not played in a regular-season game since the end of the 2023 season, making some rust inevitable. Los Angeles needs to balance its immediate defensive needs against the larger goal of having Donald healthy and effective when the season reaches its most important stretch. Garrett's absence should not convince the Rams to abandon the cautious approach that brought Donald back in the first place.

Who Needs to Step Up While Garrett Is Out?

Byron Young immediately becomes one of the most important players on the Rams defense. Young recorded 12 sacks last season and earned Pro Bowl recognition, demonstrating that he can produce without being merely a complementary pass rusher. With Garrett unavailable, however, opponents can devote more resources toward preventing Young from reaching the quarterback. The next several weeks will show whether he can continue producing when offenses know he is the primary threat coming off the edge.

Los Angeles will also need more from Josaiah Stewart, Desjuan Johnson, and Wesley Bailey. None of those players should be expected to replace Garrett individually, but collectively they can prevent the Rams from becoming too predictable. Defensive coordinator Chris Shula can rotate his edge defenders, manufacture pressure with different alignments, and potentially move players around once Donald returns to the lineup. The Rams built considerable defensive depth during the offseason, and Garrett's injury will immediately test whether that depth is as strong as it appeared on paper.

Turner and Fiske also become critical pieces of the solution. Interior pressure can make life considerably easier for edge rushers because quarterbacks have fewer opportunities to step forward when the middle of the pocket collapses. If Donald joins that group, Los Angeles could still create an extremely disruptive interior rotation despite Garrett's absence. The structure of the pass rush may change, but the Rams still have enough talent to remain dangerous if their remaining players elevate their performances.

A Difficult Four-Game Stretch Awaits the Rams

Garrett's minimum four-game absence comes during a stretch that could significantly shape the Rams' 2026 season. Los Angeles returns home to face the Giants on Monday Night Football before traveling to Denver and Philadelphia and then hosting Buffalo. That is not an ideal portion of the schedule to navigate without the reigning Defensive Player of the Year. The Rams could emerge from the stretch back in the NFC race, or they could find themselves trying to recover from a difficult opening month.

The Buffalo matchup is particularly concerning because elite quarterbacks can punish defenses that cannot create pressure with four rushers. Philadelphia presents another major challenge because of its offensive talent and ability to stress defenses in multiple ways, while Denver's offensive line will provide a significant test for the Rams' remaining pass rushers. Even the Giants’ matchup has become more important after Los Angeles opened the season 0-1. The Rams cannot afford to spend the next month simply waiting for Garrett to return.

That puts additional pressure on Sean McVay and Chris Shula to find answers immediately. Los Angeles still has enough defensive talent to win games without Garrett, but the margin for error has become smaller. The offense may also need to carry a larger share of the burden after scoring only seven points in Melbourne. A team built to win with balance could temporarily need its veteran quarterback and explosive offensive weapons to compensate while the defense reorganizes.

What Does the Injury Mean for the Rams' Super Bowl Hopes?

Garrett going on injured reserve does not end the Rams' championship aspirations. If anything, undergoing surgery now could prove preferable to allowing a knee issue to limit him for an entire season. The most optimistic scenario has Garrett returning around Week 6, healthier and more explosive than the version Los Angeles fielded against San Francisco. That would still leave the Rams with most of the regular season to rebuild the defensive chemistry they envisioned during the offseason.

The larger concern is whether this becomes a recurring issue. Garrett is 30 years old, and the Rams made a massive investment to bring him to Los Angeles because they believed he could help push an already talented roster over the top. A successful procedure followed by a healthy return would make the current setback far easier to absorb. Any complications, extended rehabilitation, or recurring knee problems would change the long-term outlook considerably.

There is also an intriguing possibility that the Rams' most intimidating defensive lineup has merely been delayed rather than destroyed. If Garrett returns healthy and Donald successfully works his way back into game shape, Los Angeles could still eventually deploy the superstar combination that made this defense so fascinating entering 2026. Add Young, Turner, Fiske, and a revamped secondary to that equation, and the Rams would still possess enormous defensive upside. The question is whether Los Angeles can remain in a strong enough position during Garrett's absence to capitalize on that potential later.

Could the Rams Make Another Move?

Garrett's injury also creates a roster question that could become increasingly important. Los Angeles could trust its existing depth and give younger pass rushers larger roles, especially if the organization believes Garrett will only miss the minimum four games. That approach would preserve resources while giving the Rams a clearer evaluation of the defensive talent already on the roster. It would also avoid making a reactionary move in response to one poor defensive performance.

However, the situation could change if Garrett's recovery takes longer than initially expected or the pass rush struggles badly over the next few weeks. The Rams have constructed this roster to compete for a championship now, which means the front office cannot simply ignore a major weakness if one develops. A veteran signing or eventual trade could become realistic if Los Angeles believes another edge defender is necessary for the postseason push. Garrett's rehabilitation and Donald's effectiveness will likely determine how aggressively the Rams need to explore those possibilities.

That makes the next month an important evaluation period for the entire organization. The Rams will learn whether Young can become the primary edge threat, whether their younger defenders can handle larger roles, and whether Donald can still dramatically influence games after two years away. They will also discover whether the Week One defensive collapse was an isolated performance or evidence of deeper problems. Those answers could determine whether Los Angeles stands pat or looks outside the building for help.

The Future of the Rams Defense Now Depends on What Happens Next

One injury does not erase everything Los Angeles built during the offseason, but Garrett's absence represents the first major test of the Rams' championship blueprint. A defense expected to overwhelm quarterbacks instead opened the season without a sack and has now lost its biggest offseason addition for at least four games. Donald's potential return gives Los Angeles an extraordinary replacement source of star power, but asking a 35-year-old coming out of retirement to immediately compensate for Garrett would be unrealistic. The rest of the defensive front must help carry the burden.

The encouraging part for Los Angeles is that the season is still only beginning. If Garrett's surgery solves the knee problem and he returns around Week Six at full strength, this setback could eventually become a relatively small chapter in a much longer season. If Donald returns effectively and the younger defenders develop while Garrett is sidelined, the Rams could even emerge with greater defensive depth than they had before the injury. But after a nightmare opening performance and the loss of their superstar pass rusher, the next four games will reveal just how resilient this supposedly Super Bowl-caliber defense really is.
