GREEN BAY, Wis. -- The Bears lost a big game to their division rivals and lost several key players to injury.
Bears coach Lovie Smith said Urlacher dislocated his wrist, and no timetable has been set for his return. Citing unnamed sources, the Chicago Tribune reported on Sunday night that Urlacher will have surgery when the team returns to Chicago. The newspaper reported that Urlacher had an X-ray at halftime, but an MRI was not needed.
"It's always tough to have your leader go down," linebacker Lance Briggs said, according to the newspaper. "He knows the defense better than anybody and he communicates everything to everyone else."
The Tribune also reported that Tinoisamoa suffered a sprained posterior cruciate ligament in his right knee.
It wasn't clear which play Urlacher was injured on, but he left on Green Bay's first drive of the second half on Sunday night. Team officials had no other details about the injury or on his possible return.
Urlacher made several plays in the first half, including when he lowered his right shoulder into the quarterback Aaron Rodgers after he had released the ball on a third down to send him sprawling.
Clark took a hard hit after making a catch in the third quarter and walked off slowly. Moments later, left guard Frank Omiyale also went down for several minutes and limped off the field.
