Philadelphia Eagles face uncertainty at starting, backup quarterback positions

PHILADELPHIA -- The only certainty in the Philadelphia Eagles' quarterback situation appears to be uncertainty -- and it doesn't end with whether Donovan McNabb will start on Sunday.

Eagles coach Andy Reid knows McNabb or Kevin Kolb will start against the Kansas City Chiefs on Sunday -- McNabb if he's healthy enough to play, Kolb if McNabb can't go.

But who's the backup?

Reid isn't sure whether Jeff Garcia or Michael Vick would be the backup quarterback.

Reid wouldn't even say that Vick is definitely playing against the Chiefs. Vick is eligible for the first time after serving a two-game suspension as the final league penalty for his role in running a dogfighting ring.

But Vick, calling himself "The Wildcat Originator," says he's ready for whatever role the Eagles have for him. The three-time Pro Bowl quarterback has not played a regular-season game since Dec. 31, 2006 with Atlanta.

"I'm very excited to have the opportunity to go out there and play football, regardless of my role," Vick said Wednesday. "This is a dream come true for me."

McNabb's injury status remains unclear, as he will not practice Wednesday because of a broken rib that forced him to miss the Eagles' 48-22 loss to New Orleans last Sunday.

Kolb made his first NFL start against the Saints, throwing for 391 yards, two touchdowns and three interceptions.

McNabb was injured in the season opener at Carolina.
