Three years ago, Arrelious Benn was one of the top wide receivers in the NFL draft and a second-round pick by the Tampa Bay Buccaneers. Injuries have derailed his career, and the Eagles acquired Benn last week by moving down 22 slots from the sixth to the seventh round and surrendering a conditional pick.

The modest price shows how Benn's stock has slipped in three seasons. But at 24 years old and at 6-foot-2 and 220 pounds, Benn still has potential.

The Eagles signed him Thursday to a one-year contract extension through 2014, so Benn will have the chance to fulfill that promise in Philadelphia. However, he was acquired to provide competition and to offer upside. There's no guarantee that he'll have a future with the Eagles.

"I'll be honest with you, I don't like my career" to this point, Benn said. "I got to stay healthy. I haven't stayed healthy. I've had a problem with injuries. And when I was healthy and out there, I made plays, and I was consistent."

Benn's best season was 2011, when he made 30 catches for 441 yards and scored three touchdowns in 14 games. He played just eight games in 2012, catching only four passes for 26 yards. He ended the season on injured reserve after he hurt his right knee.

The decline in production soured Benn's stint in Tampa Bay, and it appeared that he and the team were ready to move on. Benn expected a change to occur.

"I just needed a change of scenery, I just needed a fresh start," Benn said. "The situation just wasn't going right."
