The San Francisco 49ers believe Raheem Mostert (knee) injured his MCL, not his ACL.
He'll undergo more tests tomorrow, but it's reassuring that the team does not believe Mostert's ACL was damaged during the game. We'll know more about Mostert's outlook early in the week.
With Mostert sidelined, the 49ers leaned on Jerick McKinnon and Tevin Coleman to handle the load. Coleman led the way with 14 carries and 2 receptions, but turned those opportunities into 40 total yards, while McKinnon turned his 4 carries into 77 yards and a touchdown.
