The NMR of the wounded arm of Chicago Bers Reserve Mitchell Trubiski revealed he had a left shoulder with a slight tear in his labrum but did not need surgery, sources told Adam Scheffer on Monday on ESPN. The QB should return "sooner rather than later". Trubiski will travel with the team to London for their game against the Raiders, but is unlikely to play.
Trubiski injured his shoulder early in the first quarter against the Vikings on Sunday and missed most of his team's 16-6 victory.  The Vikings kicked Trubiski out of play in the Bears' sixth offensive game when Minnesota defensive end Daniel Hunter fired a 25-year-old quarterback for a 10-yard loss.
In the game, Trubiski's body twisted and his left shoulder hit the ground violently as Hunter pulled him down, causing the quarterback to twist. Minnesota's Everson Griffen scored the ball, though Vikings defensive end Anthony Harris sent it back to Chicago.
Trubiski immediately went to the blue tent tent before being escorted to the dressing room for further medical attention. He returned to the sideline with his left hand in the sling, watching a good portion of the game from there, and was in the locker room, congratulating his teammates after the game.
Veterans Reserve Chase Daniel replaced Trubiski and threw a first-quarter touchdown pass to running back Tarik Cohen. Daniel ran the game Sunday with no turnovers and finished 22 of 30 passing for 1
