KANSAS CITY, Mo. (AP) Kansas City Chiefs general manager John Dorsey defended the club's handling of Pro Bowl linebacker Justin Houston, who underwent surgery on his ACL last month and could miss the upcoming season.

In his first comments since news of the surgery became public, Dorsey said the Chiefs' medical staff and renowned surgeon Dr. James Andrews worked in concert in diagnosing and treating Houston's injury.

Houston hurt his left knee against Buffalo in November, and at the time he was diagnosed with a hyperextension. He returned for the playoffs but was so limited that he was rendered ineffective.

He ultimately had surgery to repair the ligament in mid-February.
