The Washington Redskins placed safety Montae Nicholson on injured reserve Tuesday with the rookie still in concussion protocol.
In a corresponding move, the Redskins promoted safety Fish Smithson from the practice squad to the active roster.
Nicholson, who was drafted in the fourth round out of Michigan State, has been dealing with a concussion since Nov. 19. He missed four straight games and Redskins coach Jay Gruden revealed Monday that he was still dealing with symptoms.
With his rookie year now over, Nicholson appeared in eight games, starting in six of them.
