Bears quarterback Jay Cutler admirably played through a groin injury Sunday against the Detroit Lions.

But he also was a marked target. And the Lions' defensive game plan was simple.

"We knew we had to keep hitting him, and keep hitting him, and keep hitting him," defensive tackle Nick Fairley said, smiling slightly. Probably because that's exactly what they did.

Cutler was bruised, battered and finally beaten right out of the game.

Detroit knocked around Chicago's wounded quarterback 10 times, and forced him from the game with an ankle injury for the Bears' final drive. Josh McCown guided a 10-play touchdown drive in his stead, but the Lions thwarted a two-point conversion to escape with a 21-19 win.

"We put it on the front four that we were going to get there and shake him up a little bit," Fairley said. "We were just like, 'we got to keep coming, and hopefully get there good enough that he will be shaken up."

Detroit didn't show any mercy.

Fairley socked Cutler four times, and sacked him once. Ndamukong Suh had four QB hits and a sack of his own.

That's eight QB hits and two sacks just from the starting tackles -- who had seven QB hits and three sacks in the previous five games combined.
