PHILADELPHIA — Michael Vick didn’t practice for the second straight day Thursday because of broken ribs, and it remains uncertain whether the Pro Bowl quarterback will play when the Eagles visit the Giants on Sunday night.

Vick broke his two lower ribs on the second play of the Eagles’ 21-17 loss to Arizona on Sunday. He didn’t tell anyone he was hurt and played through the pain.

Vince Young likely would start if Vick can’t go.

Cornerback Dominique Rodgers-Cromartie (ankle), wide receiver Jeremy Maclin (shoulder) and offensive lineman King Dunlap (concussion) also missed Thursday’s practice.
