Chicago guard Kirk Hinrich left the Bulls' game against Dallas on Monday night with a concussion after taking an elbow to the face from the Mavericks' Dirk Nowitzki.
Nowitzki was driving toward the basket when he caught Hinrich with his right elbow about 3 minutes into the game. Hinrich stayed down for several minutes before being helped to the locker room.
Hinrich was third on the team with 13.5 points per game and the leader in assists at 7.1 entering Monday's game.
