Philadelphia Eagles wide receiver DeSean Jackson

Three more Eagles hit the casualty list in this afternoon's session at Lehigh University's Goodman Campus.

Actually, one was done even before practice when guard Asante Samuel Stacy Andrews missed the afternoon event with a shoulder injury.

Then safety Macho Harris tweaked a hamstring defending a deep route.

Then defensive tackle Antonio Dixon got his bell rung and was carted off.

They joined a lengthy list of nicked-up players that already includes DeSean Jackson, Stewart Bradley and Mike Bell.

On the bright side, tight end Brent Celek had just been dehydrated during the morning session and returned to practice.

The afternoon featured mostly passing drills with an emphasis on passes to running backs. Some tidbits:

    All the quarterbacks -- Kevin Kolb, Michael Vick and Mike Kafka -- continue to have problems with passes being batted down.

    Rookie Charles Scott ran with the second team at halfback with Bell out while J.J. Arrington was on the third squad.

    Linebacker Omar Gaither picked off Vick while in downfield coverage against a wide receiver (Hank Baskett), no mean feat.

Philadelphia Eagles wide receiver DeSean Jackson, who suffered a lower back strain in training camp drills Saturday, was again held out of practice Monday morning at Lehigh University.

Jackson last year became the first player in NFL history to make the Pro Bowl at two positions -- receiver and punt returner. Jackson also missed both sessions Sunday.

Coach Andy Reid said Jackson was "doing all right," but gave no indication as to when he might return.

Two others starters, middle linebacker Stewart Bradley and cornerback Asante Samuel, were also held out of practice Monday morning because of hamstring spasms. Bradley hadn't practiced Sunday, either, and Samuel also left practice Sunday with his injury.

Reserve running back Mike Bell strained a hamstring Sunday and did not LeSean McCoy practice Monday morning.

Also missing Monday were wide receiver Jordan Norwood (hamstring) and center A.Q. Shipley (ankle). Starting guard Stacy Andrews (shoulder) and backup tight end Martin Rucker (hamstring) were injured during morning drills and did not practice in the afternoon.

Defensive tackle Antonio Dixon suffered a head injury and defensive back Macho Harris injured a hamstring during the afternoon session.
