DeSean injures left ankle

BETHLEHEM, Pa. -- DeSean Jackson injured his left ankle during Friday afternoon's practice and did not return, the Eagles said.

The wide receiver went down during a seven-on-seven drill in which he was sandwiched in between safeties Kurt Coleman and Jaiquawn Jarrett. Jackson was slow to get up and then walked to the trainer's tent. He had his left ankle tapped and returned to the action, but he did not play.

Jackson was later asked if he was OK and he gave a thumbs up.

The Eagles had an assortment of other bumps and bruises during Thursday's session but every other player finished. Guard Danny Watkins made a brief stop in the trainer's tent to get his ankle tapped. Defensive end Vinny Curry made a pit stop in the tent.

The Eagles have lost a number of players to injury since last Saturday when Andy Reid starting live hitting at practice. Defensive end Jason Babin (calf), defensive end Trent Cole (shoulder), tackle Todd Herremans (shoulder), safety Nate Allen (hamstring), tight end Brent Celek (knee), safety O.J. Atogwe (groin), and linebacker Jamar Chaney (hamstring) did not practice this afternoon.

Guard Evan Mathis missed his second day of practice because of an ear infection.

Defensive tackle Fletcher Cox was excused from Thursday's practice for personal reasons.

The Eagles worked out Ayanga Okpokowuruk, a defensive end from Duke this afternoon.
