Core Event – Torn ACL and Surgery
Defensive end Nick Bosa suffered a third ACL tear, this time to his right knee, in the San Francisco 49ers’ Week 3 victory over the Arizona Cardinals during the 2025 season. The injury limited him to three games. He underwent reconstructive surgery that also addressed chronic tendinitis in the same knee.
Background & Context – Prior Injuries and 2025 Production
Bosa’s ACL history includes a high-school right-knee tear, a left-knee tear in his second NFL season, and the recent right-knee tear. Prior to the 2025 injury, he posted 17 tackles, three quarterback hits, two sacks and two forced fumbles. The 2025 season saw the 49ers miss the playoffs after a cascade of injuries to key defenders.
Data & Statistics – Performance and Contractual Stakes
- Career accolades: Five Pro Bowls, one All-Pro, Defensive Rookie of the Year (2020) and Defensive Player of the Year (2022).
- Recent production: 18.5 sacks in 2022, 19.5 sacks and 31 tackles for loss combined in 2023-2024.
- Contract: Under contract through 2028 with a $54.9 million cap hit in 2027 and $47.1 million in 2028. A post-June 1 cut could save $32.4 million but would incur $22.4 million and $27.5 million in dead-money charges.
Official Statements & Responses – Bosa’s Rehabilitation Outlook
Bosa told MMQB reporter Albert Breer that the surgery “cleaned up” the lingering tendinitis from his high-school injury and that each ACL recovery teaches him how to condition his body for optimal speed. The 49ers have cleared him medically for the start of training camp but are limiting his workload and keeping him out of full-team drills while he progresses.
Verbatim Quotes

Why It Matters – Defensive Impact and Salary-Cap Considerations
Bosa’s return is pivotal for a 49ers defensive line that includes emerging talents Mykel Williams and rookie Romello Height. His ability to generate pass-rush pressure directly influences the team’s chances of returning to the playoffs and contending for a Super Bowl. His sizable cap commitments force the organization to weigh performance against financial flexibility, especially if a post-June 1 cut becomes necessary.
What's Next – Timeline and Team Plans
Bosa is on track to rejoin the active roster for Week 1, when the 49ers open the 2026 regular season against the Los Angeles Rams in Melbourne, Australia, per the report. The team will continue to monitor his rehab progress throughout OTAs and training camp, adjusting his snap count as needed to ensure a full-season contribution.
