After colliding mid-air with safety Nate Allen during a 7-on-7 drill this afternoon, Nnamdi Asomugha lay face down on the ground for several minutes after removing his own helmet. Asomugha held still while head athletic trainer Rick Burkholder and his crew evaluated the cornerback. Eventually, Asomugha rose to his feet under his own power, sporting a bloody lip for his efforts.

Following practice, it was announced that Asomugha incurred a lacerated lip and a sore neck and that he is being evaluated for a concussion, which is standard operating procedure. The Eagles announced Monday evening that thankfully Asomugha did not have any concussion symptoms.

"He seemed like he was doing all right. He busted his lip a little bit. I don't think it's anything too serious," said Allen, who had the wind knocked out of him but didn't miss a play. "We were in Cover 2 and I broke on the ball. Nam was there and we just collided. It's one of those plays. It happens sometimes."

Asomugha suffered a concussion last season during the Week 13 loss to the Seattle Seahawks.

With Asomugha out, Joselio Hanson took the first-team reps at right cornerback, while Brandon Hughes took over the position when Hanson slid inside for nickel packages.
