The Eagles were down a safety at practice Wednesday, with veteran safety Patrick Chung sitting out due to a bruised shoulder.

If Chung is held out, the Eagles will go with rookie Earl Wolff at free safety against Peyton Manning and the Broncos. Chung is still dealing with a left shoulder injury and has yet to practice. His status for Week four is up in the air according to Eagles defensive coordinator Billy Davis.

"I don't know.  It's up in the air," said Davis.  "He took a big jump from yesterday to today.  Hopefully every day is a jump.  With the injuries he's dealing with...  He's a tough man.  If he can go, he will go.  It's a tricky injury.  Right now I'm not sure."

The uncertainty leaves the distinct possibility that Philadelphia could be down to a rookie safety against Manning, who is the NFL's top-ranked passer in the league this year.  Manning has the most yards (1,143), touchdowns (12), and QB ratings  (137.4).  He is completing 73-percent of this passes, hasn't thrown an interception and is averaging 381 yards per game.

So hearing all those numbers, Davis did share some things that he has seen from teams that slowed down Manning in the past.

"Again, they executed well,' Davis explained.  "Within their scheme, I think they presented Peyton some looks that he wasn't familiar with.  I think it slowed him down a little bit.  I believe they had a couple turnovers that helped.  If Peyton will turn the ball over, and he hasn't yet, it levels the playing field.  Like most anybody, it's not just Peyton, it's anybody.  Really, when somebody is this efficient, the turnovers and getting them to punt, getting our offense the ball is the key."

If Chung is unable to play, the Eagles would turn to a rookie at safety: Earl Wolff, the team's fifth-round draft pick. Wolff entered the game for Chung in the second half against Kansas City last week. Wolff has also played the other safety spot, playing in place of Nate Allen who has really struggled this season.

Offensive tackle Jason Peters was able to practice Wednesday, with three fingers taped together, caused from the dislocated finger.  He will be available Sunday in Denver.

"He was trying to block one of the outstanding rushers in this league," Eagles offensive coordinator Pat Shurmur said.  "There's some good plays and then every once in a while you have a bad play.  He was dealing with a little nick on his hand.  He's doing fine."
