"With a simple proclamation, Matt Cassel tried to put to rest any doubt he would be the Chiefs starting quarterback Sunday in their regular season opener against Buffalo at Arrowhead Stadium.

"I'm good,'' Cassel said when he was asked after Monday's practice how he felt. "I'm ready to roll.''

The process may not be quite that simple. The decision rests with coach Todd Haley, who predictably wouldn't say whether Cassel's assessment of the situation was correct.

"I won't talk about any of those things,'' Haley said. "I'm assuming. He was out there at practice. He was moving around. I thought he did a good job.''

Cassel suffered a rib injury in Thursday night's final preseason game in Green Bay. He left the game in the second quarter after 340-pound defensive lineman Howard Green landed squarely on top of Cassel after a sack."
