Cooper breaks collarbone; Babin strains calf

BETHLEHEM, Pa. -- Riley Cooper fractured his left collarbone today at Eagles training camp.

The Eagles wide receiver injured his collarbone when he fell awkwardly after getting tangled up with cornerback Curtis Marsh during one-on-one drills. Cooper is entering his third season in the NFL. He was the Eagles' fourth receiver last season and played well on special teams.

"I think it's a bump in the road," Eagles general manager Howie Roseman said. "He'll recover from it. He's had a good offseason and because he's had that offseason he's gotten a lot of reps ... and gotten stronger and got more knowledge of our system and that will benefit him when he's ready to come back."

Broken collarbone injuries typically take one to two months to recover from, depending upon the break. Cooper still has to undergo an x-ray. The Eagles open the season on Sept. 9 at Cleveland, a little over six weeks from now.

Cooper's absence could allow receivers like rookie Marvin McNutt or Damaris Johnson to make an imprint with coaches. Roseman said that it was too early to say if the Eagles will add a receiver after Cooper's injury.

"We're excited about the guys on our roster," Roseman said. "Again, at any position if there's something that interest us we'll explore it."

Defensive end Jason Babin suffered a calf strain and left practice early. He will have an MRI tomorrow. The Eagles said it was not an Achilles tendon injury.

Defensive tackle Antonio Dixon left practice early with cramps.
