The Kansas City Chiefs third round pick in the 2006 NFL Draft is officially retired. Brodie Croyle told the Birmingham News that he has made the decision to retire from the NFL. Croyle spent five seasons with the Chiefs, most recently the 2010 season. He is 29 years old.

Croyle said he "knew it was time" with the injuries that piled up in his career.

"It's always tough when you've been doing something since you were a kid," Croyle said. "The surgeries, the injuries -- I wouldn't trade any of it. It was a great ride. All those things build character. All those things are placed in your life to teach you something. I definitely learned from all of them and will carry that on to the next chapter of my life."

He signed with the Arizona Cardinals for a couple of weeks last year but didn't catch on anywhere else. After Arizona, he had tryouts with the Houston Texans, Indianapolis Colts and Miami Dolphins, but didn't sign with any of those teams.

With quarterbacks in such high demand it seems surprising that Croyle is retiring but his inability to stay healthy pretty much sealed the deal for him.

Croyle retires with nine career interceptions to eight touchdowns, which means the Chiefs have still never drafted a quarterback that ended his career with more touchdowns than interceptions.
