Chiefs collapse after Jamaal Charles' injury in loss to Bears

KANSAS CITY, Mo. -- The Kansas City Chiefs failed to survive Sunday's departure of Jamaal Charles after he left the game against the Chicago Bears in the third quarter with what appears to be a significant right knee injury.

They lost the 14-point lead they held when Charles departed and fell to the Bears 18-17. The Chiefs allowed two touchdowns in the final 3:05.

The outlook for the Chiefs without Charles looks similarly bleak next Sunday at the Minnesota Vikings, and beyond. The Chiefs had yet to confirm they will play without Charles in the foreseeable future, but the signs at his departure weren't encouraging.

Charles went down after making a cut, without being hit, and immediately grabbed for the injured knee.

Charles had to be helped off the field and didn't use the injured leg as he was being assisted. After a brief examination by medical personnel on the sideline, Charles was then taken to the locker room. The Chiefs announced shortly afterward that he was done for the day.

The Chiefs led 17-3 when Charles left the game and didn't score again. He was replaced by Charcandrick West, who joined the Chiefs last year as an undrafted rookie.

West finished with 31 yards on seven carries. The Chiefs' other running back, Knile Davis, carried twice for 2 yards.

One reason to get excited: After allowing more than 30 points in each of their previous three games, the Chiefs held the Bears without a touchdown until late in the final quarter. Excitement has to be tempered after they allowed two in the final 3:05, especially considering the Bears played without starting left tackle Jermon Bushrod and wide receivers Alshon Jeffery and Eddie Royal.

One reason to panic: West has played little for the Chiefs after spending most of last season on the practice squad. He might not be ready to be a featured back, even if he winds up sharing the job with Davis.

Fantasy watch: After two games with 140-plus yards, wide receiver Jeremy Maclin had 85 yards on eight receptions.

Ouch: Charles was the injury of note.
