49ers' Raheem Mostert (knee) to miss around 8 weeks

The San Francisco 49ers will place running back Raheem Mostert (knee cartilage), who is expected to miss roughly eight weeks, on the injured reserve.

What It Means:

Mostert, who has always been one of (if not the most) explosive offensive players in the NFL, suffered a knee cartilage injury that will now sideline him for roughly eight weeks and will require a stint on the injured reserve. Mostert has been electric whenever he has been on the field, but has struggled with unlucky injuries perhaps more than any other running back in the league.

Mostert went down early on in Week 1, paving the way for Elijah Mitchell to carry the ball 19 times for 104 yards and a score. We'll see how things shake out in Week 2 with 2021 third-round pick Trey Sermon likely joining the mix, but Mitchell should be one of the top waiver wire adds heading into the second week of the season.
