Matt Cassel will start for the Kansas City Chiefs with Brady Quinn ruled out of Thursday's AFC West game at San Diego.
Quinn, who is 3-11 in his career as a starter, didn't finish Sunday's game against the Raiders because of concussion-like symptoms. Cassel has been a turnover machine, and the Chiefs have 25 giveaways, an NFL-worst.
Head coach Romeo Crennel said Monday that it would be Quinn's job if everyone was healthy. But Tuesday, he said Quinn is out for the game. Quinn had been elevated to the starting role during the Chiefs' bye week.
"We'll evaluate Matt and we'll evaluate (third-string quarterback Ricky) Stanzi also."
Cassel said Sunday he was planning to prepare as if he would start Thursday's game but will be the 'same guy' no matter what Crennel decides.
"We have to turn the page, and focus on San Diego," he said. "One thing this group or any of us is going to do is give up. ... I haven't been part of a season, either, where we've had so many things go wrong. .... I've never been around a team where we've had this many things go the wrong direction. At some point, the luck's got to change and go our direction."
