Bosa (knee) dealing with tendinitis

During a media sessions late Monday, Morris was asked if Bosa would be able to go in Week 1 against the Rams, to which he responded, “Oh, he’s going out there. He’s going.” There’s no room left for interpretation about that quote, meaning Bosa is expected to make his return to the field after tearing his ACL in Week 3 of the 2025 season. Don’t expect a normal allotment of snaps in his first game in almost a calendar year, but the veteran pass-rusher can still make a significant impact when on the field. IDP managers will want to confirm his status on the team’s injury report Tuesday before making plans to insert him into Week 1 lineups.

Bosa suffered a torn ACL in Week 3 last year and is still working his way back. He was back on the practice field today and is on track to play in Australia versus the Rams next week. Bosa got off to a hot start last year, logging a sack in each of his first two games before exiting Week 3 a few snaps in. If he can return to form quickly, the 49ers defense should take a step forward this year.

Shanahan noted that the tendinitis that has been bothering Bosa has been “subsiding” over the past few days. The 28-year-old defender missed Tuesday’s scrimmage against the Chargers, but it sounds like he should be back in action in a relative short time.

Barrows notes that Bosa will “likely get ramped up in practice over the next two weeks or so.” It doesn’t sound like he’s expected to be a full go just yet, but it’s always a good sign for a player coming off an ACL tear in the previous season when he avoids the PUP list to start camp. Bosa totaled two sacks and nine tackles in just three games last season, but had totaled nine or more sacks in each of his previous four seasons. Still only 28 years old, Bosa should have plenty to offer the Niners’ defense once he’s back in full and getting after the quarterback.

Williams suffered a torn ACL in Week 9 last season and was seen doing resistance bands workouts at the team’s facilities last month. The second-year pass rusher totaled 11 tackles, four TFLs, and one sack in his rookie season before going down, and is one of a handful of players the Niners are hoping to have back on the defensive side of the ball. Veteran pass rusher Nick Bosa (knee), who also suffered a torn ACL last season, is also working his way back to the field and said he is “pretty far along” in his recovery. If either player is unable to go by the start of camp, they will likely be added to the PUP list with a chance to be activated when they clear all medical and conditioning tests.

Bosa has been rehabbing this offseason after tearing his ACL early in November. He said he is “far along” in the recovery process and should be good to go for the 2026 season. Bosa tore his right ACL in high school and his left ACL in 2020. Although having experience in this department is less than ideal, Bosa said his prior experiences have helped him during this rehab process.

Fellow EDGE Nick Bosa (also knee, also ACL), who suffered his injury six weeks earlier, is expected back for Week 1. It sounds like Williams is in more doubt. Based on that, it’s certainly possible the second-year EDGE player starts training camp on the PUP list. 49ers beats saw Williams doing side-to-side movements and working with resistance bands at rookie minicamp, so he’s certainly active, but he still has several hurdles to clear in his rehab before a return is on the table.

Roughly two months ago, 49ers general manager John Lynch told reporters that both players were expected to return sometime “around” training camp, so today’s report confirms that they generally remain on track. We do not yet know when they are expected to be full-go, though, so things are still a little fluid. Bosa, 28, suffered a torn ACL on September 21st. Williams, 21, reportedly hyperextended his knee on August 7th and later tore his ACL as well on November 2nd.

The 49ers did a simple restructure on Bosa’s contract, according to NFL Network’s Tom Pelissero, creating $17.1 million in cap space. The 28-year-old defensive lineman is still due $23.1 million this season while his cap hits in 2027 and 2028 are now over $100 million combined. Bosa played just three games in 2025 after tearing his ACL in the first month of the season, but is expected to be available sometime around training camp.

The news comes straight from 49ers general manager John Lynch, though the 49ers’ injury updates have been less than reliable over the past 18 months. Bosa, 28, tore an ACL on September 21. Williams, a 21-year-old first-round rookie, tore his on November 2. The 49ers are a candidate to bring in more EDGE depth in the draft or late free agency given how much injury uncertainty they’ll carry there in 2026.
