Eagles defensive tackle Beau Allen suffered an upper body injury in the chest/pectoral area last week, according to sources. The injury is expected to require surgery.
The Eagles had no comment.
Allen’s injury occurred while he was working out on Thursday, so it happened after the Eagles acquired defensive tackle Tim Jernigan.
Allen, 25, is entering his fourth season with the Eagles. He was expected to compete for a starting spot with Jernigan after Bennie Logan left in free agency.
The 6-foot-3, 327-pounder, who has been in negotiations about a contract extension with the Eagles, played in all 16 games in each of his first three seasons. He played 40 percent of the defensive snaps last season, started three games and finished with 29 tackles and a half of a sack.
“Obviously with free agency and Bennie not being here ... it gives him an opportunity to step in there and really show what he can do, if he can be the guy and compete and handle that load,” coach Doug Pederson said in March.
The Eagles return Pro Bowler Fletcher Cox at defensive tackle and added Jernigan. They also have reserve Destiny Vaeao, practice squad holdover Aziz Shittu and Justin Hamilton, who was signed to a reserves/futures contract in January.
