Kansas City, Mo. ? The new starting quarterback of the Kansas City Chiefs is a former first-round draft pick on a one-year deal whose career thus far has been a disappointment.

His backup is a team captain whose long-term contract made him the face of the franchise.

Chiefs coach Romeo Crennel announced Monday that Brady Quinn will be under center when the Chiefs play Oakland on Sunday, and Matt Cassel will serve as the backup for the foreseeable future after struggling mightily through the first five games of the season.

“I felt like the most impactful move I could make to get everybody’s attention was to change the quarterback,” Crennel said. “I think that will get everybody’s attention, and hopefully that impacts the team because the quarterback position is the one that has the spotlight on him.”

Crennel said he informed both quarterbacks he was making a change Monday morning. The rest of the team learned of the move shortly before practice.

“Look, I’m excited about the opportunity,” Quinn said. “There’s always pressure, but pressure is what you make of it. As a quarterback in this league, you’re used to it.”

Quinn started for the first time since 2009 in a loss at Tampa Bay two weeks ago, when Cassel was still feeling the effects of a concussion sustained the previous week against Baltimore.
