BETHLEHEM, Pa. — The biggest injury concern for the Philadelphia Eagles after Saturday morning’s practice was wide receiver DeSean Jackson.

By the end of the afternoon, the really bad news was that tight end Cornelius Ingram’s rookie season had ended before it started.
For the second straight year on almost the same day, Ingram tore the anterior cruciate ligament in his left knee. The extent of the injury, which will require season-ending surgery, was revealed during an MRI examination Saturday.
Ingram was injured Tuesday, one day before the one-year anniversary of the same injury that cost him his senior season at the University of Florida.
“He tore the ACL on the same knee that he had the surgery on in a goal-line drill here,” coach Andy Reid said after the Eagles’ afternoon practice at Lehigh University. “He just hyperextended and it popped on him. Obviously, it’s a shame for the kid. He’s a great kid and he’s worked very hard.”
Down to just two healthy tight ends in starter Brent Celek and undrafted rookie Eugene Bright, the Eagles signed Rob Myers, an undrafted rookie from Utah State. 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.
The news on Jackson was much better.
“DeSean is all right,” Reid said after the receiver left the morning practice with a hyperextended right knee.
Jackson banged knees with cornerback Asante Samuel during a one-on-one drill and was immediately sent to the medical tent for treatment. He was later carted from the field, but said he was fine after practice.
“I’m all right,” he said, offering a thumbs-up gesture. “No problems.”
Jackson, however, did not take part in the afternoon special-teams practice, and left the morning session with a sleeve on his right leg.
Even though this is only Jackson’s second season, he still ranks high among the offensive players the Eagles can least afford to lose. He set a team record for rookie receiving yards last season, catching 62 passes for 912 yards while playing in all 16 games. He added 11 more catches for 207 yards in the Eagles’ three playoff games.
Ingram was the Eagles’ second player in seven days to have his season ended by a torn anterior cruciate ligament. Starting middle linebacker Stewart Bradley suffered one in his right knee in Sunday’s practice at Lincoln Financial Field.
The loss of Ingram was significant because the Eagles had hoped to use several two-tight-end sets with the rookie and Celek, a third-year veteran. The Eagles are now paper-thin at that position, with veteran Matt Schobel the only tight end besides Celek with any NFL experience.
Schobel has been sidelined for most of this week by a sore calf muscle.
Ingram, a fifth-round pick, said after the morning practice that he wasn’t allowed to talk about the injury but that he hoped to be back on the field for the afternoon practice. Reid said the Eagles’ medical staff was surprised by the results of the MRI exam. Indeed, Ingram had practiced on a limited basis Thursday, two days after suffering the injury.
Injuries have hit the Eagles hard at this training camp, and a cloud of uncertainty still remained over right offensive tackle Shawn Andrews, who had yet to step on the practice field because of soreness in his surgically repaired back.
However, the injury news along the offensive line was akin to the recent economic news: It got a little better.
Left tackle Jason Peters and right guard Stacy Andrews, who had suffered quadriceps and knee injuries, respectively, returned to practice, although neither participated in the live hitting sessions. Peters said he was ready to take part in live drills, but the team is being cautious.
“I could have went today, but I don’t want to rush anything,” Peters said. “We have a couple more weeks before the season starts and we have a couple of preseason games, too.”
Peters spent the afternoon working with trainer Rick Burkholder on the field.
Four Eagles remained on the physically unable to perform list: Shawn Andrews, running back Brian Westbrook (ankle), defensive tackle Trevor Laws (hamstring), and defensive end Victor Abiamiri (pectoral muscle).
