The San Francisco 49ers season took a big swing on one player. Quarterback Jimmy Garoppolo suffered a knee injury in the fourth quarter, and head coach Kyle Shanahan said after the game that the trainers think it is a torn ACL. Garoppolo will undergo an MRI on Monday when the team returns to Santa Clara, at which point they will know for sure.
Whatever the injury ends up officially being, Garoppolo is out indefinitely, and that means the backup quarterback gets the call. C.J. Beathard takes over as the starting quarterback, and Shanahan said the plan is to promote Nick Mullens from the practice squad to serve as his backup.
