– The season appears to be over for Pro Bowl running back Jamaal Charles. It might be for the Kansas Chiefs, too.

Jay Cutler led Chicago to a pair of fourth-quarter touchdowns Sunday, the second an alert toss to Matt Forte with 18 seconds remaining, giving the Bears an 18-17 victory after the Chiefs star running back suffered what appears to be a torn anterior cruciate ligament in his right knee.

"I knew we needed to make some plays in the fourth quarter. I trust the guys around me," Cutler said after leading the Bears (2-3) to their second victory in a row. "I know all I've got to do is get the ball out to them and they'll do most of the hard work."

It was the fourth loss in a row for the Chiefs (1-4), who play the Vikings at TCF Bank Stadium next Sunday.

"You're put in a situation like this, you have to make plays," coach Andy Reid said. "We didn't do that."

The Chiefs led 17-3 in the third quarter when Charles went down while trying to make a cut. The preliminary diagnosis was a torn ligament and he will have a magnetic resonance imaging exam Monday.

With him out of the game, the Bears quickly seized the momentum. After Robbie Gould's second field goal got them going, Cutler led an 88-yard drive that he capped with a 22-yard pass to Marquess Wilson with 3:05 left. The two-point conversion came up short, but the Bears defense responded by forcing a quick three-and-out.

With help from a pass interference call on rookie Marcus Peters, the Bears quickly moved downfield. That's when Cutler took a snap from the shotgun, dropped the ball, picked it up and spotted Forte running past safety Husain Abdullah in the end zone for the go-ahead score.
