Safety Malik Mustapha likely to miss start of 49ers season with ailing knee
“Mustapha’s injury is actually related to the ACL tear he suffered in the same knee while playing at Wake Forest in January 2022. Mustapha returned from that injury in time to play 10 games during the following season.
Although Mustapha departed the Arizona game with a knee injury and did not return, he was thought to be OK and in the locker room with the team the day after the game. Later that week, an MRI revealed that the graft that had been placed in the knee was torn.
