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.
