The San Francisco 49ers have been dealt a significant blow to their defensive line ahead of the 2026 season opener. Starting defensive tackle Alfred Collins is set to miss the entire campaign after sustaining a torn patellar tendon during a practice session in Melbourne, Australia, on Tuesday.

Head coach Kyle Shanahan confirmed the severity of the injury on Wednesday, noting that the defensive lineman will require surgery. The incident occurred just before the team transitioned into 11-on-11 drills, marking a premature end to what was expected to be a breakout second season for the former second-round draft pick.

Defensive depth concerns for 49ers

The loss of Collins is compounded by the recent news that defensive end Sam Okuayinonu has been placed on injured reserve. Okuayinonu is scheduled to undergo surgery this weekend to address a broken foot, leaving the 49ers thin in the trenches before their first game of the year. Coach Shanahan expressed his disappointment regarding the situation, acknowledging the difficulty of losing two key defensive contributors in such quick succession.

As the team prepares for Thursday night’s clash against the Los Angeles Rams, the coaching staff is evaluating their remaining options. With Collins sidelined, the active roster features C.J. West and rookie Gracen Halton as the primary candidates to start alongside Osa Odighizuwa. The situation is further complicated by the status of undrafted rookie James Thompson Jr., who has been limited in practice due to a hamstring injury. To bolster the line, the 49ers may look to elevate practice squad members Sebastian Valdez or Kevin Givens.

Injury updates on Bosa and Kittle

While the defensive line faces personnel challenges, there is more positive news regarding other key starters. Coach Shanahan indicated that the team is planning for the return of defensive end Nick Bosa, who is recovering from a right ACL injury, and tight end George Kittle, who is working back from a right Achilles issue. Both players are expected to be available for the season opener against the Rams.

Despite their availability, the coaching staff remains cautious about their workloads. Shanahan emphasized the need to manage both players carefully as they return to competitive action, noting that while they have looked sharp in training, the team must be smart about their usage during the game.
