The Eagles suffered another major loss to their wide-receiver corps when Arrelious Benn tore the anterior cruciate ligament in his left knee Tuesday sidelining him for the season. Benn is the third player on the Eagles to tear his ACL in two weeks and the second wide receiver. A former second-round pick Benn was acquired in March and had the chance to earn a starting job after Jeremy Maclin suffered a torn ACL on the second day of training camp. The team was intrigued by his skills and potential but his injury history caused him to fall out of favor with the Tampa Bay Buccaneers. Those injury problems reemerged on the first day of camp when Benn was sidelined with a knee injury. He missed more than a week and did not return until Sunday. Benn had only two full practices before Tuesday's injury. The team also cut wide receiver Dave Ball. Ball had been out with quadriceps and hand injuries. The Eagles now have only nine healthy receivers and have two open spots on the 90-man roster. They will have three spots when they place Benn on injured reserve.
