CHICAGO (AP) — Jay Cutler shook off an apparent rib injury, Brian Urlacher made a key fumble recovery and the Chicago Bears won their fourth straight, beating the Detroit Lions 13-7 on Monday night.

It was certainly not an easy night for the NFC North leaders, particularly their quarterback, but they came away with the win after a week off and possibly buried Detroit (2-4) in the process despite getting a major scare along the way.

That happened in the second quarter when Cutler was sacked by Ndamukong Suh and ultimately wound up going to the locker room to have his ribs examined.

Cutler started the second half and was 16 of 31 for 150 yards and a touchdown in the game, but with the defense locking down the Lions, the Bears (5-1) prevailed. It was a huge blow for last-place Detroit, a team many expected to contend for the division championship after making the playoffs for the first time in more than a decade.
