Chiefs have another banged-up QB

Posted by ESPN.com's Bill Williamson

One of the potential replacements for starting quarterback Matt Cassel, who may not be able to play on opening day because of a knee injury, appears to be banged up as well.

Joel Turner, the agent for Kansas City quarterback Tyler Thigpen, said his client is playing with two broken ribs, which Turner says Thigpen suffered in the first preseason game. Thigpen did not play in the second preseason game, but he did play in the third one, spelling Cassel after he was hurt on the third play of the game against Seattle.

“Tyler is a tough guy,” Turner said. “He's fighting through this injury like nothing happened. People just don't know how tough Tyler is.”

Thigpen or Brodie Croyle would replace Cassel if he can't play Sept. 13 at Baltimore. ESPN's Adam Schefter is reporting Cassel may be able to play when the Chiefs open the season. Cassel has an MCL sprain. Kansas City coach Todd Haley would not address Cassel's situation Monday.

Schefter also reports that Thigpen will not be traded. Turner said he and Thigpen are not focused on a trade at all and Thigpen is looking forward to the season.

Turner said he believes Thigpen, who played well last season when he took over at midseason, can succeed in the NFL.

“I don't think a lot of people on the outside, especially some media people, know how good Tyler can be,” Turner said. “He comes from Coastal Carolina so he doesn't get a lot of respect. But if this guy came from a big-time program like USC, Michigan or Notre Dame, people would be high on Tyler … This kid is a playmaker.”

Turner said Thigpen plans to work through his broken ribs and will be available if the Chiefs plan to use him.
