49ers open 21-day practice window for SS Malik Mustapha

The 49ers have officially opened the 21-day practice window for star strong safety Malik Mustapha, who has been on reserve/PUP after suffering a torn ACL in the 49ers week 18 game last year against the Cardinals.

Hopefully Mustapha will be ready to go as soon as possible, as he’d be a great boost to the 49ers defense, which has yet to get an interception.

The San Francisco 49ers today announced they have opened the practice window for S Malik Mustapha (Physically Unable to Perform List)
