BETHLEHEM, Pa. - The Philadelphia Eagles' recent streak of bad luck was extended Saturday.

An MRI taken earlier in the day revealed that promising rookie tight end Cornelius Ingram has retorn the anterior cruciate ligament in his left knee. The news came nearly one year to the day after he tore it the first time while at the University of Florida.

"Obviously, it's a shame for the kid," coach Andy Reid said in quotes provided by the team. "He's a great kid and he's worked very hard."

Ingram, a fifth-round draft pick, apparently suffered the injury during a goal-line drill last Tuesday at Lehigh University. He sat out Wednesday and Thursday with what the team had termed inflammation, but it was not expected to be serious.

He had the MRI more as a precautionary measure.

"It looks like he just hyperextended it a little bit (during Tuesday's practice)," Reid said. "He remembers getting folded over, but his leg was in the air when it happened. It wasn't one of those things that just killed him (in pain) when it happened."

Although Reid did not announce it, Ingram is expected to have surgery and will likely miss the entire season.

Ingram became the second key Eagles player to suffer a major knee injury in the last week. Last Sunday, they lost starting middle linebacker Stewart Bradley for the year with a torn right ACL. Bradley got hurt during a non-contact drill at the Eagles' Flight Night at Lincoln Financial Field in Philadelphia.

Elsewhere on the injury front, tackle Shawn Andrews has yet to practice during training camp because of lower-back pain. Wide receiver DeSean Jackson left Saturday's morning workout with a hyperextended right knee and is listed as day-to-day.

The Eagles also have been forced to deal with the death of longtime defensive coordinator Jim Johnson, who lost his battle with cancer two weeks ago.

Ingram was expected to play a significant role in the offense this season as a backup to starter Brent Celek. Because Matt Schobel is also nursing an injury (strained calf), Celek and rookie free agent Eugene Bright were the only tight ends on the field Saturday morning.

The Eagles sought to add some depth there by signing rookie free agent Rob Myers on Saturday afternoon. Myers, from Utah State, originally signed with the New York Jets after the draft but was released May 29. Like Ingram, Myers also did not play last season. He missed 2008 with a turf toe injury that required surgery.

To make room for Myers on the 80-man preseason roster, the Eagles released undrafted rookie punter Ken Parrish.
