Immediately following the game, 49ers head coach Jim Harbaugh said that the initial diagnosis was damage to Bowman’s ACL, but it appears that there could be even more damage to his knee than initially determined.
According to Pro Football Talk, a league source says that the 49ers fear Bowman suffered both an ACL and MCL injury. San Francisco is waiting for an MRI to determine the full extent of the injury, but it has not yet been conducted.
The injury is a devastating blow for the 49ers defense, because it will keep Bowman out of action throughout the offseason and will likely land him on the PUP list to start the season — which means he would have to miss at least six games.
We will update you with more information as it becomes available, but the initial diagnosis for Bowman is not good.
