Jamaal Charles goes on injured reserve with season-ending ACL tear

The Kansas City Chiefs placed Jamaal Charles on season-ending injured reserve after he was diagnosed with a torn ACL in his right knee. Charles went down without contact in Sunday's game against the Chicago Bears and immediately grabbed his knee. He was in obvious pain on the field, and was eventually helped up by trainers.

He couldn't put weight on the leg as he limped off the field with the help of the training staff and teammate Justin Houston. He was also helped to the locker room, again putting no weight on the injured leg.

Charles sustained an ACL tear in the other knee in 2011, playing in just two games that season.

Charles had 12 carries for 58 yards and caught one pass for 26 yards before going down with the injury. He's Kansas City's starting running back and one of the best players on that team. Coming into the game, he had 59 carries for 306 yards and four touchdowns, and has rushed for over 1,000 yards in each of the past three seasons, and in two other seasons earlier in his career.

Charcandrick West is the primary backup to Charles, with Knile Davis behind him on the depth chart. When Charles sustained the injury, West had two carries for 15 yards and Davis did not have a carry against the Bears.
