Not sure if this is good news for Michael Vick or not, but the injury that knocked him out of the Philadelphia Eagles game against the Atlanta Falcons is being called a neck injury, not a concussion. He appeared alert while moving to the sidelines and being checked out by medical personnel, so a concussion might've been something of a surprise.
A minor neck injury would permit Vick to return to the game if he's able, while any sort of a concussion would rule him out for the rest of the night.
Vick suffered the injury when a blitzing William Moore spun him into an Eagles lineman. He hit face-first and was seen spitting up blood on his way to Philly's sideline. Mike Kafka took over in relief, as backup Vince Young is inactive for this game.
