Bears middle linebacker Brian Urlacher could miss at least the next three games with a right hamstring injury, an NFL source confirmed on Tuesday.

Urlacher suffered the injury on the second to last play of the 23-17 overtime loss Sunday to the Seattle Seahawks. He waved for assistance at the end of the play, which was a 12-yard completion from quarterback Russell Wilson to receiver Jonathan Baldwin. On the next play, receiver Sidney Rice scored the game-winner from 13 yards out.
