49ers' Nick Bosa week to week with knee tendinitis

San Francisco 49ers defensive end Nick Bosa is being managed on a week-to-week basis after being diagnosed with tendinitis in his surgically repaired right knee, head coach Kyle Shanahan said Tuesday. The star pass rusher, who is recovering from a torn ACL suffered last season, has now missed five consecutive practices, including a joint session with the Tennessee Titans.

Shanahan addressed reporters after Tuesday's practice, explaining that the tendinitis is a common setback for players returning from anterior cruciate ligament injuries. "Just soreness, tendinitis," Shanahan said. "It's a pretty normal thing with ACLs... It's a normal thing, and that's why we've got to be smart here for week to week. But I'm feeling no concerns about him being any more than that."

The coach emphasized that the team is taking a cautious approach to ensure Bosa is fully healthy for the regular season. Bosa, 28, suffered the knee injury in a September 21, 2025, game against the Arizona Cardinals and underwent surgery five days later. He made just three appearances during the 2025 campaign before the season-ending injury.
