Niners HC Kyle Shanahan told reporters Monday that Edge Nick Bosa tore his right ACL in Sunday's win over the Cardinals. Shanahan said after the game that a sideline ACL test gave them hope the ligament might be intact. But Bosa will now miss the rest of the season.

Niners Edge Nick Bosa left Sunday's win over the Cardinals with a right knee injury, and there's reason to believe it could be serious. Bosa flashed a thumbs down toward someone in the stands as he limped to the locker room after leaving in the first quarter.

Niners Edge Nick Bosa and LB Dre Greenlaw are active for today's game against the Dolphins. Both entered the day questionable but appeared likely to play. LB De'Vondre Campbell says he doesn't care.

Niners Edge Nick Bosa and LB Dre Greenlaw are active for tonight's game against the Rams. Bosa returns after missing the past three games with an oblique injury. He managed just a single limited practice, though, in a walkthrough. Bosa remains a risky play for IDP lineups. Greenlaw's making his 2024 debut. He has been out since suffering an Achilles' tear in the Super Bowl. That makes it tough to know what kind of playing time we can expect from the LB. He's best left on fantasy benches this week. The San Francisco defense can only benefit from getting the stars back, though.

Niners LB Dre Greenlaw is questionable for Thursday night's game against the Rams after putting in a full practice Wednesday. It was merely a walkthrough, but also the first time Greenlaw has been listed as a full participant since returning to practice ahead of the Week 13 game. Edge Nick Bosa is also questionable after returning to a limited practice Wednesday. San Francisco also ruled out rookie S Malik Mustapha.

The 49ers expect Edge Nick Bosa to miss his third straight game this week. Bosa's officially doubtful after missing all three practice days with the hip and oblique injuries that cost him the past two games. He has participated in just one practice since Week 10.

Niners Edge Nick Bosa (rib) and CB Charvarius Ward (hamstring, knee) are active for today's game against the Rams. Both look ready for IDP use as planned.

Niners Edge Nick Bosa is officially questionable for today's game against the Rams. But ESPN's Adam Schefter reports that he's expected to play.

We'll confirm his status when inactives are announced.

The 49ers have agreed to a five-year, $170 million extension with Edge Nick Bosa, according to multiple reports. The pact ends Bosa's holdout ahead of Sunday's opener against the Steelers and makes him the highest-paid defensive player in the league. We never moved Bosa down the preseason or weekly IDP rankings for this situation. The star has already proved he can deliver on little practice time.

The 49ers don't expect Edge Nick Bosa to report with the rest of the team for the start of training camp. There's no injury to worry about, though. GM John Lynch says the two sides are trying to find the "sweet spot" on a long-term extension that's a "little more complicated," according to ESPN's Nick Wagoner. Bosa has shown throughout his still-young career that he can deliver even after limited practice time. So this shouldn't alter your draft plans in your IDP league. Bosa hasn't moved in our IDP rankings.

ESPN's Adam Schefter reports that 49ers EDGE Nick Bosa (hamstring) "will play" today vs. the Buccaneers. That's significant for both IDP lineups and the 49ers' team defense. Bosa did sit out of practice all week, but he's still worth betting on for your fantasy football lineup. We've seen him effectively play through hamstring injuries before.
