Arrington is listed as questionable.
''You would never say never, but I think it would be hard,'' Redskins coach Joe Gibbs said when asked about Arrington's chances for Sunday's game against Philadelphia.
Arrington participated mostly with the scout team and admitted he was nervous before taking the field. He hadn't done much since his surgery in September because of a bone bruise that showed up on an MRI. That scared doctors, who feared Arrington could make it much worse by pushing himself hard to return.
''The mental part is all right,'' Arrington said. ''It's just going to be a matter of getting back into the groove physically. There is no way to simulate what goes on out on the field except by doing it. It takes time to get back into the swing of things, but I felt good.
''I couldn't sleep well last night knowing I was going to have the opportunity today. I was back on the field, back in my palace. It was good. It was definitely good. But I don't know, we'll see what happens.''
. . . Also, the Redskins placed defensive end Phillip Daniels on the Injured Reserve list. He was replaced on the roster by Cedric Killings, cut by the Redskins this summer.
. . . Defensive end Demetric Evans is out for Sunday with an ankle injury. Among those not practicing: Laveranues Coles (toe), Walt Harris (hamstring), Robert Royal (knee), Randy Thomas (hamstring), James Thrash (hamstring). All are listed as probable.
For the Eagles: DE Derrick Burgess (sternum) and LB Nate Wayne (hamstring) are out. DE Jerome McDougle (knee) is doubtful; G Artis Hicks (knee), RB Reno Mahe (ankle) and G Jermane Mayberry (calf) are questionable.
