Eldra Buckley

• Running back LeSean McCoy missed practice with a quadriceps contusion, the Eagles said. The severity of the injury is unknown at this time but it does not appear to be serious. A contusion, in layman's terms, is a bruise, and McCoy probably received one of those dings that many NFL players get nowadays because they often don't wear thigh pads.

• With McCoy out and Mike Bell nursing a calf strain, Eldra Buckley moved up to the first team and Martell Mallett played with the backups. Mallett even got some repetitions with the starters during a "live" red zone period.

• The first team offense took on the first team defense, the first time this camp that the starters faced off in a full-contact period. The result was a draw. The offense scored twice with Kevin Kolb passing to Mallett underneath and the tailback running into the end zone both times. The last score came on a shovel pass. Defensive end Juqua Parker read the play, but Mallett carried Parker and just crossed the line. Or did he? It was close and the defense protested. Eagles coach Andy Reid called it a touchdown. We'll check the tape.

• Mallett hyperextended his left knee when the second team units butted heads. He went to the trainer's tent to get a look-see, but he was able to walk off the field. J.J. Arrington made an appearance at practice after missing the last week or so with a foot contusion.

• WR Chad Hall once again took reps with the running backs during individual drills and played some halfback during team drills.
