As with any head related injury, the team followed the league mandated concussion protocols and the All Pro corner was not found to have any symptoms.
Andy Reid said this morning that Asomugha has whiplash, but never blacked out and does not have a concussion. At this point all signs point to the Eagles having dodged a bullet on this one.
"Nnamdi has whiplash-type symptoms and a split lip," said Reid. "He didn't have a concussion. He's been tested. Everything's okay there. He wasn't knocked out. That's not what happened when he was hit. He was completely conscious the whole time. But he did get a pretty good laceration to his lip and his back of his neck is a little bit sore."
The incident occurred when Asomugha and Allen both attempted to break up a Michael Vick pass intended for DeSean Jackson. The two collided in midair and went down hard. Allen got up and resume practice, but Nnamdi was down for several minutes before taking a cart ride back to the locker room.
This is probably a good time for a caution about how any Eagles injury is covered by the national media. You'll often see the phrase "so and so was carted off" at Eagles practice. While that is actually true, it does give an overly negative connotation. You think of gameday where if a guy has to be carted off the field, he almost certainly has a major injury. At Lehigh, since the fields are so far away from all the facilities, players will take a golf cart ride for almost anything they have to leave the field for. In this case, Nnamdi rode in the front seat.
So, not that its untrue that he was "carted off," but just remember to keep the context in mind.
The Eagles will hold a full workout this afternoon. Asomugha will not practice today, but will be day to day from then on.
