Pederson said Wallace will miss a couple of weeks, but said the team does not yet plan to put Wallace on injured reserve. That means the team is hoping Wallace will return this season.
"We're still going to evaluate," Pederson said. "He still has a few more tests. It's a fracture. That's going to be a couple weeks."
Wallace was injured in the first quarter of the Eagles' 27-21 loss to the Tampa Bay Buccaneers on Sunday.
Alshon Jeffery remains "week to week" while recovering from rotator cuff surgery in the offseason. He still has not been cleared for contact.
