Eagles cornerback Nnamdi Asomugha was carted off the field after colliding with safety Nate Allen during Monday's practice.
Asomugha was on the ground for several minutes before walking to a cart under his own power.
Following practice, it was announced that Asomugha has a lacerated lip and a sore neck. He is also being evaluated for a concussion.
Asomugha suffered a concussion during a Week 13 loss to the Seattle Seahawks last season.
