Philadelphia Eagles wide receiver Riley Cooper suffered a fractured left collarbone at training camp Saturday and could miss a month or more.
Cooper, a third-year player who caught 16 passes for 315 yards last season, fell awkwardly when he and cornerback Curtis Marsh collided during one-on-one drills.
"I think it's a bump in the road," general manager Howie Roseman told Philly.com. "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."
Also, defensive end Jason Babin suffered a calf strain and was scheduled for an MRI on Sunday. It was not thought to be serious.
