Injuries ruined the 49ers season in 2020 and are already starting to take a toll on this year’s roster.


Already without cornerback Jason Verrett and running back Raheem Mostert due to season ending injuries, today it was reported that starting linebacker Dre Greenlaw had surgery to repair a groin injury leaving San Francisco without its starting weakside linebacker for up to eight weeks.


Greenlaw played 37 snaps in a season opening victory over Detroit, however he did not return to the game after returning an interception of Jared Goff for a touchdown just before halftime.


The 49ers have made a number of moves this week to fill the gaps caused by the injuries. The team signed cornerback Dre Kirkpatrick and running backs Kerryon Johnson along with claiming Trenton Cannon off waivers to fill the openings left by the injuries to Verrett and Mostert. The team also signed linebacker Curtis Bolton to their practice squad.


It is expected that Azeez Al-Shaair will step into Greenlaw’s position, while Demtrius Flannigan-Fowles steps into the starting lineup to replace Al-Shaair.


Flannigan-Fowles played safety collegiately at the University of Arizona and made the move to linebacker after signing as an undrafted free agent in 2019. He spent all of his first season on the practice squad before making the active roster for 2020.


Flannigan-Fowles played in 11 games in 2020, finishing with nine tackles. He made his first career start in a week 17 loss to the Seattle Seahawks in place of Dre Greenlaw.


Against Detroit in week one, Flannigan-Fowles played 39 total snaps with 17 coming on defense. He would finish the game with three tackles, a career high.

    1. How painful is FFS?
      Fortunately, most patients report that the pain after FFS is no worse than a headache or hangover. You are prescribed painkillers to take for a few days after the operation, but in many cases a basic analgesic like paracetamol/acetaminophen is enough to manage any discomfort.

  1. This team just can’t catch a break. At this point all options should be on the table. Need to look at sacrificing a sea chicken in the locker room or maybe barbecuing a Ram at Lynch’s house for a team picnic. Maybe hold a hunt for some Cardinals. Must do something to break this curse.

  2. For anyone interested here is an interesting film breakdown of some of the plays SF ran against the Lions.

    Jack, these could make for some interesting offseason (or even in season) articles on how SF might attack an opposing O / D or how plays are used to set up other plays. Just food for thought

    1. Hey Shoup,

      I have a number of film breakdowns on my youtube channel. NFL Gamepass does not have the All-22 film currently available. Some folks have figured out a workaround, but I haven’t had the time. I will be doing weekly film breakdowns once it becomes available again.

  3. Well Jack, What are you going to do about posters who continue to post their political views despite your previous request. I doubt they will ever stop. They will always use an excuse to do so unless you stop them. So you are faced with a decision – which course of action will cause you to loose the least number of readers. Good luck and hopefully you will be successful in turning this into a successful FOOTBALL blog.

      1. Jack, as long as you permit posters with blatantly provocative politically oriented screen names, essentially giving them a political pass with every posting, your admonitions ring entirely hollow. Sorry to say.

        1. Jack, be consistent and block Jerry, Mel and the double and triple posters . Gav/1.6 (same person) clearly has a a chemical imbalance and multiple personality disorder. Are we really to believe that these people just wandered in and are distraught over a few posts.

        2. If they comment on football I don’t have a problem with it and everyone should be mature enough to not take it in another direction. If they choose to comment about politics those will be deleted. This really should not be that difficult.

          1. dumb – just focus on your writings

            You want to start policing comments – who cares if it’s health or politics ?

            Just do your job and let people talk – scroll past or ignore comments you don’t like

            If you are someone/those complaining about Politics on a blog – it just means you have a low IQ and can’t think independently or you are so unstable you can’t ignore a comment by an ANONYMOUS person –

            @Jack these are loofs you want to follow ?

            Note – You are not paid, rated or judged by the comment section – word to the wise “stay in your lane”

            If you care so much – call the IT team and have them make all users comment only with their real names as usernames.

            1. If you care so much – call the IT team and have them make all users comment only with their real names as usernames.

              One, not a good idea. You saw what happened to Seb once his RL info was revealed here. Unfortunately there are a lot of unbalanced cretins trolling boards like this. While there should be some sort of account verification, why would PD start now when they haven’t the 10-15 years this board has been up?

              1. I know it’s not a good idea – am hoping Jack realizes he is powerless and this is not a battle he needs to get into.

          2. If they comment on football I don’t have a problem with it and everyone should be mature enough to not take it in another direction. If they choose to comment about politics those will be deleted. This really should not be that difficult.

            You really have a blind spot on this Jack. The names are politics personified even before posting word one. So we are supposed to be mature enough to not take the political provocation they are rubbing in the blogs face, but any another mention of politics is forbidden, because… other posters aren’t mature enough ignore those? And OMG must be removed! What you are doing is setting one set of rules for some, another set for others. OK, whatevs…. your blog, your set of rules.

            1. exactly – why even get in the middle of it – wasting energy on people without faces

              it’s like Jack does not understand he is on a new level – but wants to remain in the previous level

              reminds me of a house pig who feels more comfortable in a sty.

              1. One, I think there should be moderation. Just don’t do it differently for different subsets of posters.

              2. yes of course there should moderation – not sure Jack should waste his time on it.

                and at some point we just have to agree this is not something you want to control on the blog (kinda like transporting water in Stainless-Steel Colander) ….

                I say it’s best to ignore

  4. I am leaving this blog, due to the commentary that has no relation to the Niners and to the NFL. Perhaps some editorial control will be installed to eliminate toes irrelevant posts; I will check back later to see if that’s the case.

  5. The Niners lost 3 starters in their first game to injuries, 2 of which are season ending. So far it doesn’t look like it is going to be any different this year from last year. Something is mighty wrong here. I realize that all teams suffer injuries but it sure seams the Niners have it worse than most. Staley has suggested that maybe the team is not in football shape,
    I guess there are two thoughts on this subject among football people. One that reducing physical activity and hits will reduce injuries and another that more physical activity reduces injuries once the season begins. What ever it is, I think the Niners need to do some real soul searching because if they are doing something wrong here, it needs to get fixed.

    1. Low IQ? How about the geniuses who can’t ignore someone who has a name they don’t like or the genius who wants to ban me and Mel because we don’t want this football blog to be consumed by politics.

      This discussion is existential to this blog. If political comments are allowed to continue, it will consume the blog and football readers will leave. There are plenty of places for political comments, but this is a football blog and calling others dumb and have low IQs doesn’t help anything.

      1. Yes low IQ

        if you don’t want the football blog to be consumed by politics -PAY FOR IT NOT TO HAVE POLITICS

        A – CONTRIBUTE YOUR MONEY TO HIRE SOMEONE TO MANAGE COMMENTS

        B – JUST IGNORE THE COMMENT YOU DON’T LIKE

        Which of the above do you think someone with a brain will choose?

      2. Low IQ? How about the geniuses who can’t ignore someone who has a name they don’t like or the genius who wants to ban me and Mel because we don’t want this football blog to be consumed by politics.

        Dude, those names some people don’t like are burning down the blog with their in your face political handles. I have as much right to call them out as you do the political comments. You ignore the political names, fine. Then why are you so pissy about political comments which are the exact same thing?

        1. Because I don’t agree with you that a “handle” is the same as opining on your politics and you and Bruce Lee were doing this long before these 2 names showed up. So everyone is supposed to ignore your political postings but you can’t ignore a name you don’t like?

          1. No I can ignore a name. It’s just hypocritical on the moderators part to allow posters to express political opinions through names in an otherwise policed non political space. If you don’t agree with that you are just as hypocritical as well.

  7. @Jack Hammer –

    FYI – your writings or articles not that bad but nothing major here – it’s mediocre at best.

    My advice is spend more time learning how to write like a professional instead of a blogger. – and less time in the comment section.

    1. Do you find that insulting people who have a different opinion makes you feel better about yourself? Does it make you feel more intelligent?

      1. there is a difference in opinion and difference in stupidity

        nobody should be spoon feeding you comments to read – you have a choice to ignore

        that is not insulting someone – that is common sense

          1. exactly key word “criticize” – not insult

            Jack better expects criticism and praise from commenters – its part of his job

            see how my Low IQ comment is not an insult but more of a fact.
