Five days ago, the 49ers activated defensive lineman Glenn Dorsey from injured reserve with designation to return. Per a league source, Dorsey nevertheless remains a few weeks away from being ready to play.
Dorsey suffered a torn biceps in August; he’s listed as out for Sunday’s game with a forearm injury. Defensive coordinator Vic Fangio said recently that Dorsey’s recovery has plateaued.
The problem for the 49ers comes from the decision to activate Dorsey. He would have remained on IR/DFR until ready to play. By activating him, they had to make a move to permit Dorsey to count toward the 53-man roster.
