The Eagles will be without two starters against the Arizona Cardinals Sunday, head coach Andy Reid said in his press conference Friday. Safety Nate Allen (concussion) and left guard Evan Mathis (turf toe) will both be listed as out on the injury report. Defensive end Juqua Parker, who has been struggling with a high ankle sprain, will be listed as questionable after being a limited participant in practice throughout the week.

Reid said that Allen has not yet passed his concussion tests and was a bit limited by the short week leading up to the game after last Monday night's game.

"I think he'll be alright for next week," Reid said of Allen.

Rookie second-round pick Jaiquawn Jarrett will make his first NFL start in place of Allen, while King Dunlap, 6-9, will start his first game as a guard in place of Mathis.

"King's worked in (at guard) throughout training camp and throughout the season," said Reid. "Seems a little strange to people, but the offensive linemen are all familiar with him. He jumps in there ... he has some game experience ... he'll be fine."

On defense, the Eagles are prepared to face second-year quarterback John Skelton, rather than former Eagle Kevin Kolb, who is unlikely to play because of a turf toe injury.

"We're prepared for both guys," said Reid. "You have to. I probably think that Skelton's gonna play as opposed to Kevin, but we have taken time to make sure we're prepared for both.

"(Skelton) has been there for a couple years so he knows their system."
