Who will step up with Babin and Cole out?

BETHLEHEM, Pa. -- Another day, another injury.

Trent Cole had swelling in his AC shoulder joint after Monday's practice and will be sidelined for an extended period. Eagles coach Andy Reid did not have a specific timetable for the defensive end's return. 

"He's got swelling in there," Reid said Wednesday after the morning walkthrough at training camp. "Rick [Burkholder] tried to get it calmed down last night. Came back this morning it was swelling a little bit more this morning that it even was yesterday. We get that swelling down he'll be back. Could be a day, could be a week."

Both of the Eagles' starting defensive ends are now on the shelf. Jason Babin has a calf strain and will be out for 2-3 weeks. Cole and Babin's absence will allow the next ends on the depth chart to get additional repetitions with the first team.

“I know some of the young guys can benefit from me being out there which is ultimately going to benefit the team. So that’s a part I wish I could be out there for," Babin said. "It's upsetting, but I’m going to get out there as fast as I can.”

It was then pointed out to Babin that the younger players -- like Brandon Graham, Phillip Hunt and rookie Vinny Curry -- could also benefit from his absence by getting to play against better competition. He was asked who he thought would benefit the most.

“I think that person will probably emerge at the end of this week," Babin said. "It will be obvious to everyone … I got a guy in mind.”

Veteran Darryl Tapp will also be in the mix. The Eagles typically carry five ends on their 53-man roster, which would likely mean Tapp and Hunt could be battling for that last spot. The Eagles could just end up carrying six.

Graham has taken the majority of Babin's reps since he left practice Saturday. Defensive tackle Cullen Jenkins has also seen snaps on the outside. Babin will miss the first preseason game on Aug. 9 against the Steelers, which would mean Graham will likely get the start.

Cole could also be out for that game. He didn't seem too concerned about his injury.

"I'm always ready," he said.

Tight end Brent Celek appears close to returning from a knee sprain. He ran on one of the unused fields at Lehigh Wednesday morning. Celek injured his knee on Thursday during the first full squad practice.

“I don’t see me being out too terribly much longer," Celek said. "That’s up to the trainers to decide that type of stuff, but I’m starting to feel better."

Reid said that safety Phillip Thomas (hamstring) was still out, but was improving.
