Though he participated in a morning walk-through practice, Eagles quarterback Mike Vick was absent for the first official practice of the week on Wednesday afternoon.

The Eagles officially disclosed on their injury report that Vick missed practice due to the concussion that he suffered against the Falcons on Sunday night. It remains unknown whether Vick will be able to play on Sunday against the Giants.

Also absent were defensive end Juqua Parker (ankle) and Darryl Tapp (pectoral).

Fully participating, despite injuries, were safety Nate Allen (knee), tight end Brent Celek (hip), defensive end Trent Cole (hand), receiver Riley Cooper (hamstring), tight end Clay Harbor (ankle), linebacker Akeem Jordan (shoulder), tackle Winston Justice (knee), linebacker Brian Rolle (quadricep), cornerback Asante Samuel (finger), receiver Steve Smith (knee), and quarterback Vince Young (hamstring).

Young’s ability to fully participate means that he could be the guy who gets the call, if Vick can’t play. Mike Kafka replaced Vick on Sunday, because Young was still fighting an injury that he suffered in the preseason finale.

UPDATE 5:43 p.m. ET: The team has not disclosed whether Young or Kafka took the snaps with the first-team offense on Wednesday. Which means that we won’t know until one of the 53 players on the team yaps about it.
