The fifth-year defensive end injured his right triceps in the Philadelphia Eagles' preseason opener and likely will miss the rest of the season. Running back Ryan Moats also could be done for the year with an ankle injury.

McDougle was competing for a job on a crowded line and wasn't a lock to make the roster. He has just three sacks in 33 career games.

"He was competing like a lot of other guys," defensive coordinator Jim Johnson said Wednesday. "It's too bad. He was having a good camp. But that's part of the game."

The Eagles traded up and selected McDougle out of Miami with the 15th pick in the 2003 draft. He missed the first eight games of his rookie year with ankle, knee and hip injuries, sat out five games in 2004 and spent the following season on the sideline after he was shot in the abdomen by robbers.

Moats, a third-round pick in 2005, also was hurt in Monday night's 29-3 loss to the Ravens. He broke his left ankle on a running play in the second half. Coach Andy Reid said Moats will have surgery soon.

Moats has 347 yards rushing and three touchdowns in two seasons, averaging 4.5 yards per carry. Filling in for the injured Brian Westbrook during his rookie year, Moats had 114 yards rushing, including a 40-yard score, against the New York Giants. He followed that with a 78-yard effort that included a 59-yard scoring run at St. Louis.

But Moats struggled to earn playing time last season and was inactive for eight games. He was competing for a job as the fourth or fifth back.
