49ers' Mostert out 8 weeks with torn knee cartilage
The injury bug continues to bite the San Francisco 49ers.
Starting running back Raheem Mostert will be out eight weeks with torn knee cartilage, head coach Kyle Shanahan said Monday.
Mostert left Sunday's game against the Detroit Lions after two carries for 20 yards. Elijah Mitchell stepped in and recorded 104 yards and a touchdown in the 41-33 victory.
Mostert won the 49ers' starting job in a loaded backfield, but injuries have followed him throughout his seven-year career. He was limited to eight games in 2020 after bursting onto the scene with 772 yards and eight touchdowns in 2019.
Rookie running back Trey Sermon will be active for Week 2, Shanahan said, per David Lombardi of The Athletic. The third-rounder was inactive for the season opener after he missed time during training camp.
Shanahan also said he remains optimistic that Jeff Wilson will be able to contribute this season, per Lombardi. His original return timeline from a torn meniscus was October at the earliest.
The 49ers visit the Philadelphia Eagles in Week 2.
