BETHLEHEM, Pa. -- For the second straight year, tight end Cornelius Ingram's season is over before it started.

The Eagles' fifth-round pick from the University of Florida suffered a torn anterior cruciate ligament in his left knee during a goal-line drill Tuesday. The extent of the injury was revealed during an MRI examination this morning.

It is the same knee and the same injury that cost Ingram his final season at the University of Florida last year at almost the exact same time.

"It was in a goal-line drill," coach Andy Reid said. "He just hyperextended it and it popped on him. Obviouslsy it's a shame for the kid. He's a great kid and he's worked hard. He was doing some good things."

Earlier in the day, Ingram said he couldn't talk about the injury and that "he hoped to be back for the afternoon practice."

Down to just two healthy tight ends -- starter Brent Celek and undrafted rookie Eugene Bright -- the Eagles signed undrafted rookie Rob Myers this afternoon. Myers, 6-foot-4 and 243 pounds, was originally signed by the New York Jets after the draft but released in late May. After catching 21 passes for 320 yards and three touchdowns as a junior, he missed his entire senior season with a turf toe injury. To make room on the roster, the Eagles released punter Ken Parrish.

Ingram is the second Eagles player in less than a week to suffer a season-ending torn ACL. Middle linebacker Stewart Bradley tore his right ACL during Sunday's practice at Lincoln Financial Field.

Jackson appears fine

DeSean Jackson hyperextended his right knee when he got tangled up with cornerback Asante Samuel during the morning workout. The wide receiver immediately went to a tent to receive treatment and was eventually carted off the field.

He told reporters after practice that he was fine. The team didn't give a prognosis on when Jackson would return.

"I'm all right," Jackson said, offering a thumbs up. "No problems."

Reid also said he thought Jackson would be fine following the afternoon practice.

"He's all right," the coach said. "They just banged knees."

Jackson has had a phenomenal camp, but today's setback could limit his preparation for Thursday's preseason opener against the New England Patriots. He did not take part in the special teams practice.

In other injury news, guard Stacy Andrews (knee) and tackle Jason Peters (quadriceps) were back in full pads. They did not partake in live hitting, however. Andrews took a day of rest on Thursday. Peters had been working out with the training staff.

Running back Brian Westbrook (ankle), defensive end Victor Abiamiri (pectoral muscle) and defensive tackle Trevor Laws (hamstring) continued to rehab with the team's trainers. Shawn Andrews (back) remained out.
