Mostert's knee injury not a torn ACL, Shanahan says


The 49ers already have bitten by the injury bug to start off their 2021 season, with running back Raheem Mostert being ruled out of Sunday’s Week 1 game against the Detroit Lions with a knee injury.

Coach Kyle Shanahan said after the 49ers finished off a 41-33 win that the injury is not ACL-related.

Mostert was in the game for just the first two drives and finished with two carries for 20 rushing yards. Rookie Elijah Mitchell replaced him and immediately made a contribution, including a long touchdown run.

Last season, Mostert tallied 677 yards with three touchdowns.

San Francisco is pretty thin at the running back position now. In addition to Mitchell, the team has JaMycal Hasty and Trey Sermon. However, Sermon was inactive for today's game.
