Raheem Mostert – Running Back – San Francisco 49ers I don’t know what’s up with the 49ers injury bug, but it continued in 2021 with an early injury to Running Back Raheem Mostert. Now Mostert is no newbie to injuries but coming so early in the season is almost laughable at this point. Mostert was seen on the sidelines after his injury, but news just came out today that he will most likely miss the next eight weeks and will be placed on IR. Whether or not that happens, it doesn’t sound good. Look for Elijah Moore and JaMycal Hasty to be big waiver wire additions this week. Healthy scratch Trey Sermon may also get some carries now.
