The Kansas City Chiefs have placed Jamaal Charles on injured reserve.

Charles tore his ACL last season and didn't look like the same player coming back this season.

Charles began having soreness in his surgically repaired right knee two weeks ago.

A source told ESPN that Charles will have what is described as a "hopefully pretty minor procedure done [on the knee] tomorrow.

The IR designation could mark the end of Charles' career in Kansas City. His contract with the Chiefs runs through 2017, when he is scheduled to make $3,750,000 with a roster bonus of $3 million.

Spencer Ware has been productive for the Chiefs in place of Charles.
