Quinn's First Professional Practice Today

BEREA, Ohio (AP) - Brady Quinn is practicing with the Browns today, after ending his holdout by signing a five-year contract last night.

The former Notre Dame quarterback missed 16 practices while the Browns negotiated an incentive-laden deal with his agent, Tom Condon. They began talks in May, but didn't make significant progress until last weekend.

Before joining his teammates for a practice closed to fans and media, Quinn said the business side of football was a difficult lesson to learn, calling his holdout "tough" and "frustrating."

The Browns picked Quinn with the 22nd overall pick in April's draft after trading a 2007 second-round pick and their first-round pick in 2008 to the Dallas Cowboys.

He's fourth on the depth chart behind Charlie Frye, Derek Anderson and Ken Dorsey. But Frye and Anderson are having mediocre camps, so Quinn could be challenging for the starting job soon.

Quinn says one of his goals is to start as a rookie.
