Chiefs aren't shedding any light on Cassel's status

Matt Cassel doesn’t know whether he’ll be healthy enough to be the Chiefs’ starting quarterback Sunday, but he was at least healthy enough to answer questions Thursday about his sprained left knee — and what that means for his immediate future. In the time normally set aside for the starting quarterback’s news conference, Cassel said he was making progress since suffering the injury early in the Chiefs’ third preseason game. He has participated in practices this week. But in individual drills on Thursday, Cassel still appeared to run with a limp.
