"We've had a great week of preparation, a lot of hard work, and it definitely has sunk in," Foles said. "I'm ready to go."
Vick, meanwhile, will be resting this weekend, and spending time "in dark, quiet places," according to head trainer Rick Burkholder, who spoke to reporters at the Eagles training facility on Friday.
"He has too many symptoms for us to even exercise him," Burkholder said.
Cutler won't play
Jay Cutler will miss Monday's game at San Francisco because of a concussion, leaving the Bears without their starting quarterback. The team announced the decision Friday, meaning Jason Campbell is the likely starter against the 49ers.
Coach Lovie Smith would not say if Cutler will make the trip to San Francisco. Players need to be cleared by team physicians and an independent neurological consultant before they can return, under NFL safety protocols. It's possible that the Bears could hold him out even if he gets the OK from doctors.
The 49ers, meanwhile, could be without QB Alex Smith, who suffered a concussion of his own last week.
Ditka has stroke
Hall of Famer Mike Ditka has had a minor stroke, an ESPN producer said.
Seth Markman posted on Twitter that the former Chicago Bears coach and player fell ill Friday and will not appear on the network's NFL shows this weekend. Markman wrote that Ditka "wanted everyone to know he's ok."
Ditka told the Chicago Tribune he was feeling "good right now and it's not a big deal." He was playing cards aFriday when he noticed his hands "weren't working quite right," and he then started having difficulty speaking.
