49ers DE Nick Bosa Has Torn ACL, Done For Season

Sep. 27: In addition to the torn ACL, Bosa sustained further cartilage damage in his left knee, as Adam Schefter of ESPN.com reports. The 49ers are hopeful that the extra damage will not delay Bosa’s return, and the club remains optimistic that he will be back in time for the start of the 2021 campaign. Bosa will undergo surgery this week.

Sep. 21: Nick Bosa is done for the year. The 49ers announced that their star pass rusher has indeed suffered a torn ACL in his left knee. This doesn’t come as much of a surprise, as head coach Kyle Shanahan hinted at the injury following yesterday’s win.

The injury is obviously a massive blow to the 49ers defense, as the reigning Defensive Rookie of the Year was establishing himself as one of the top rushers in the game. The former second-overall pick earned a Pro Bowl nod last season after compiling 47 tackles, nine sacks, and a forced fumble. He had another forced fumble during the 49ers’ Week 1 loss to the Cardinals.

If there’s any consolation, Bosa should be good to go for the start of next season. Plus, other than core muscle surgery during his time at Ohio State, Bosa has generally stayed healthy during his playing career.

The 49ers are dealing with injuries throughout their roster. It sounds like defensive tackle Solomon Thomas also suffered a torn ACL, while defensive end Dee Ford is sidelined with a neck injury and cornerback Richard Sherman is sitting on IR with a strained calf. The offense isn’t immune; the team has a depth-chart worth of wideouts sidelined (including Deebo Samuel), tight end George Kittle is dealing with a knee ailment, and running backs Raheem Mostert and Tevin Coleman will be out this weekend against the Giants. Fortunately, it sounds like quarterback Jimmy Garoppolo‘s high-ankle sprain isn’t too serious.

The team has already added Ziggy Ansah to their squad, and it wouldn’t be shocking if the organization signs some more depth along the defensive line.

      I’ve seen this elsewhere. Exactly how does playing more help prevent injuries?

      • wishyouwerehere

        I think the thought is if they have preseason they only have to play a few series or a quarter at a time. Going right to playing a full game prob has some effect here

      • yaketymac

        I mean, it’s not like runners run marathons after not training beforehand.

        I wasn’t really making a controversial point.

        • JJB0811

          I didn’t say it was controversial. But each preseason, we endlessly boo after watching starters get carted off. One season w/o the games and we want them back?

          I don’t know the answer; more practice reps, less preseason reps? But I can’t honestly think playing more will help prevent injuries in such a physical game.

          Cam Newton lost his season last year because of a preseason injury. As one example.

    • HailRodgers12$

      I’d say less to do with preseason games, maybe more to do with off-season organized workouts/mini camps/etc.

    • Yep it is

      He we go again with the No Pre Season. How many times has a player been injured in pre season and then the claim is “ useless preseason”. Violent sports have violent injuries. Give it a break on the Pre season crap

  1. Oooof

    Bosa didn’t play any preseason ball last year either. Between this year and his last college season, couldn’t you just as easily argue he’s injury prone? (I’m not arguing that, just making a point about the preseason claims.)

    • yaketymac

      Yeah it’s not just about Bosa.

      If you’re on this site you presumably follow football. Look at all the injuries through 2 weeks.

      Want to make the argument the NFL should do away with preseason games every year? Let’s hear it. Otherwise who cares that you like being a contrararian?

      • Oooof

        It’s not about being a contrarian. It’s about not leaping to conclusions because of one crazy weekend. Many of these guys have already had serious injuries or been banged up. In McCaffrey’s case, he played 93% of his team’s offensive snaps last year. Are we really gonna blame the lack of preseason?

        Lots of guys have suffered preseason injuries in past years that couldn’t this year. Every season has tons of injuries. They don’t all get evenly spread out. There will inevitably be weeks with extra ones.

        I’m not saying this weekend wasn’t unusually horrible and alarming, but people are over-eager to reach conclusions about why when it’s just as easy to conclude that it’s a statistical outlier of a week. It might be the abnormal offseason and lack of preseason, don’t get me wrong. But I’m not being contrarian when I suggest that’s far less certain as an explanation than people are making it out to be.

      • I’m not sure why your immediate impulse is to argue and insult, @yaketymac. Several people have simply engaged you in conversation and you’ve responded defensively with condescension and insults. There’s no need for it. No one is disrespecting your opinion.

  2. joeyrocafella

    MLB has a lot of injuries this season as well. It’s crazy to see the number of players that are having major injuries in both sports

    • yankeefan363

      Not getting proper post season workouts games being canceled double headers

  3. Ed "The Mythical One"

    Seeing lots of ACL/Knee, and lower leg injuries this season. Did the NFL/teams start using some sort of new PAT (prescription athletic turf)?

  4. crosseyedlemon

    It’s never too early to provide excuses for a regression that was inevitable (with or without injuries).

  5. The Mistake of Giving Eugene Melnyk a Liver Transplant

    Let’s hope he takes this time to learn and educate himself, because he is one of the stupidest people in the NFL.

  6. nentwigs

    Although ZIGGY has been added to pick up the slack,


    is nowhere to be found !!

  7. angt222

    Crazy how in one week madd players all go out with season ending injuries

  8. jessaumodesto

    I hate to say it, but this may be the end of the line for Joey Bosa
