Brian Urlacher and D.J. Moore each collected turnovers to stifle potential second-half touchdown drives, and the Chicago Bears beat the Detroit Lions, 13-7, in Chicago on Monday night.

It was the fourth straight win for Chicago (5-1).

The Bears led 13-0 when the Lions threatened in the third quarter, advancing the ball to the 1-yard line before Urlacher recovered a fumble by Joique Bell of Detroit (2-4). Quarterback Matthew Stafford drove the Lions back into the red zone three possessions later, only to have Moore intercept his pass from the 3-yard-line.

Chicago quarterback Jay Cutler finished 16 of 31 for 150 yards and a touchdown, but he left the game for much of the second quarter after injuring his ribs after being sacked by Ndamukong Suh. He returned in the second half.

Brandon Marshall caught six passes for 81 yards and a touchdown for the Bears, while Matt Forte ran for 96 yards. Stafford was 28 of 46 for 261 yards and a scoring pass. Lions' wide receiver Calvin Johnson had just three catches for 34 yards.
