[Kansas City.com] Quarterback Matt Cassel appeared on Kansas City’s practice field Monday for the first time since injuring his left knee on Aug. 29, but his status for Sunday’s opener at Baltimore remained unclear.

Cassel was in full uniform Monday and did most of the conditioning drills in the short period the media were permitted to watch. If he does not start at Baltimore, the Chiefs would probably go with Brodie Croyle.

Coach Todd Haley was evasive whether Cassel would play Sunday.

“I think that as the week goes on, we’ll know a little bit more,” said Haley. “We’ll know a little bit more with Matt for sure. But it was good that he was out there. He was able to get through some things. As the week goes on a little further, we’ll know a little more as far as where he’s at.”
