Westbrook back in Philadelphia; Brown and Peters practicing

One day after his visit with concussion specialists in Pittsburgh, Eagles running back Brian Westbrook was back at the NovaCare Complex beginning his attempt to return to the football field this season.

Westbrook was not on the practice field, but he was in the building and based on what he was told by doctors at the University of Pittsburgh Medical Center Wednesday, it definitely seems possible that he will return before the end of the season.

Dr. Joseph Maroon, a neurosurgeon employed by the Pittsburgh Steelers, and Dr. Michael Collins, a neuropsychologist, said in a statement that Westbrook "has an excellent prognosis" and the doctors "expect a full recovery" for the veteran running back. Westbrook is scheduled to go through another battery of tests in two to three weeks, according to Maroon and Collins, which means the running back probably will not return until at least some time next month.

The best news on the practice field for the Eagles was that cornerback Sheldon Brown and offensive tackle Jason Peters were participating.

Brown said Wednesday there was "a good chance" he'd be able to play Sunday night against the Chicago Bears after suffering a strained hamstring in the second quarter of the team's loss at San Diego. He was a limited participant in practice for the second straight day.

Peters, after missing Sunday's game in San Diego with a sprained right ankle, was a full participant in practice.
