Nick Bosa’s week took a bad turn on Thursday, and the early read is that the 49ers may be without their defensive star for a while.
NBC Sports Bay Area’s Jennifer Lee Chan first raised the alarm after Bosa showed up on the injury report with a calf issue. On her YouTube channel, she said there was concern the pass rusher may have suffered a “serious calf injury” and suggested the setback could stretch well beyond a single game.
Here’s the full quote from Lee Chan:
“Nick Bosa was supposed to talk to us on media day, that was Wednesday. He did not talk to us on Wednesday, then he did not talk to us today, on Thursday.
We waited around for him. Knee and calf.
It’s not good. I just..it doesn’t feel good.
My spidey sense is saying that this is a serious injury for Bosa. If he’s not out for the season, he’s out for multiple weeks.”
Bosa missed most of last season after tearing his ACL in the Week 3 win over the Arizona Cardinals, the same opponent the 49ers are set to face this Sunday in their third game of the season.
Lee Chan later walked back part of her initial read in a tweet, but the bigger update came from Adam Schefter, who reported that Bosa will miss a few weeks after pulling his calf in practice on Thursday. Ian Rapoport added that Bosa could end up on injured reserve.
For San Francisco, the timing couldn’t be worse. The 49ers’ pass rush was absent without Bosa in 2025, and a long absence would put real strain on a defensive line that already doesn’t have much depth.
The unit showed signs of life in the first two weeks, pressuring Matthew Stafford throughout the season-opening win over the Los Angeles Rams and then piling up four sacks of Malik Willis in the Week 2 blowout of the Miami Dolphins. Bosa’s ability to collapse the pocket was a major reason that second performance looked so dominant.
If he’s sidelined, a young group will be asked to carry a lot more of the load.
Kyle Shanahan is scheduled to speak at 1:35 PT, about an hour after 49ers practice, and Bosa’s status is sure to be the main subject as San Francisco prepares for a division game that already has plenty of weight attached to it.

49ers Suddenly Have A Bigger Nick Bosa Problem Than Arizona
Nick Bosas latest setback leaves the 49ers facing more than just a one-game absence against Arizona. The star pass rusher was officially ruled out because of a calf injury he suffered in practice, and the outlook is now stretching beyond this weekend. San Francisco is still weighing whether to put him on injured reserve, a decision that would signal a longer detour for one of the leagues most important defenders.
The bigger concern is the broader health picture around Bosa, whose knee has been watched since training camp. What started as routine maintenance has now turned into another week-to-week question for a team that counts on him to shape games at the line of scrimmage. For a 49ers defense built around pressure up front, the timing makes the absence feel larger than the Cardinals matchup itself. [Read more 🡒]
49ers Week 3 Injury Picture Centers On Two Crucial Veterans
The 49ers Week 3 injury picture is starting to come into focus, and it carries a familiar kind of weight for a team trying to keep its defense in rhythm. San Francisco and Arizona both put out their injury reports ahead of the matchup, with some players working back into practice while others stayed on the sideline, leaving the final availability list unsettled with one more practice still to come.
What stands out most is how much attention the 49ers linebacker group continues to draw from the other side. Cardinals quarterback Jacoby Brissett and head coach Mike LaFleur both singled out the duo for the way they play, a sign that San Franciscos front seven still commands respect even as the injury report adds a layer of uncertainty heading into the weekend.

Nick Bosa Injury Just Put A Massive 49ers Decision In Play
Nick Bosas latest injury has done more than cloud the 49ers outlook for the coming months. It has also pushed a difficult long-range roster question back into focus, because San Francisco is now staring at a 2027 decision involving one of the leagues premier pass rushers and a contract that will be hard to ignore if the injury uncertainty lingers.
The financial angle is the part that makes this so complicated for the 49ers. Bosa carries a major cap hit, and his recent injury history only sharpens the pressure on a front office that may eventually have to weigh a pay cut, an outright release with dead money attached, or a post-June 1 move to soften the cap consequences. For a team that still builds around star talent, it is the kind of decision that can reshape both the roster and the payroll. [Read more 🡒]
