Reid did not have a timetable for Asomugha's return, but he said the team would take it "day-by-day" with their starting right cornerback.
The Eagles are off on Wednesday and return to the NovaCare Complex on Thursday to continue their preparations for the season. They travel to New England on Monday to face the Patriots in their second preseason game.
If Asomugha can't play, the Eagles have a number of options to replace him. Curtis Marsh has been the third outside corner on the depth chart, but he's been out for days with a hamstring injury.
Joselio Hanson and Brandon Hughes have taken practice repetitions at Asomugha's spot since his injury. When Hanson moved outside from his nickel corner position, rookie Brandon Boykin took his place.
No update on Patterson
The no news on Mike Patterson's return was news in itself.
The Eagles originally said that the defensive tackle would miss all of training camp. But the team left Lehigh on Tuesday to return to the NovaCare Complex on Thursday and Patterson's condition had yet to be updated.
"Right now, we're waiting just to see how it's going to work out," Reid said. "We're strictly banking on what his doctor says and he hasn't given us any updates on him."
Patterson had brain surgery in January to correct an arteriovenous malformation. The Eagles originally said he was on track to return by camp, but on the first day head trainer Rick Burkholder said that doctors didn't feel comfortable letting the defensive tackle return to practice.
Burkholder said there was a chance Patterson could miss all of the preseason and possibly more time. Patterson, 28, has been here for all of camp working out mostly in the weight room. He said he was disappointed by the doctor's orders, but hoped to be back soon.
"The doctor's been on vacation for a while, so he's just kind of getting back here and getting back in the swing," Reid said.
Patterson, who is currently on the physically unable to perform list, was listed as a starter heading into camp. Derek Landri has taken his place, although Fletcher Cox, Antonio Dixon and Cedric Thornton have all taken turns starting alongside Cullen Jenkins.
Reid said that he will play his starters for at least a half against the Patriots. The Eagles travel to take on the Browns four days later, and Reid isn't expected to play his first team much since he opens the regular season at Cleveland. . . . Linebacker Jamar Chaney (hamstring) is closer to a full return, Reid said. . . . Former Eagles defensive back and assistant coach Jimmy Carr, 79, died Monday in Fishers, Ind. Carr played nine seasons in the NFL, including 1959 to '63 for the Birds. He was the starting left cornerback on the 1960 NFL championship team. He was an NFL assistant coach for 24 years and spent 1970-71 with the Eagles as defensive coordinator.
