Buffalo Bills coach Dick Jauron would not commit himself Wednesday to a quarterback choice beyond this week's game in Miami.
J.P. Losman is the starter for now, but it's clear Jauron is reserving the right to make a change depending on how Losman plays.
Asked if Losman was not the starter for the foreseeable future, Jauron said:
"I don't know that we want to talk about the rest of the year, we're just talking about the Miami Dolphins. We're focused on them and that's where we want to stay. The quarterbacks that we have, I couldn't be happier with the way they've performed and grown in the position. . . . What's happened to this point has kind of been dictated by injury and then by performance. We'll just keep moving along here and hopefully we won't change a lot. But we don't know the answer to that."
Jauron acknowledged that Losman's strong performance was the big factor in the decision to keep him on the field.
Trent Edwards did throw the ball in practice Wednesday, but Jauron termed his participation as limited.
"He's made a lot of progress, no doubt about that, because last week he couldn't grip a football," Jauron said. "He participated on a limited basis and threw the ball pretty well. He's not back to where he needs to be to play in a game. I'm not sure he'd be confident going on the field right now and playing in an NFL game, but maybe by the end of the week he might be. . . . So he's progressed a lot in the last three days, but he's not back to playing shape."
Linebacker John DiGiorgio (concussion), receiver Roscoe Parrish (thigh) and tight end Derek Schouman (ankle) each sat out practice. Schouman has a high-ankle sprain and probably is out for several weeks. Parrish is questionable. DiGiorgio said his injury was not serious and he expects to play Sunday.
Miami Dolphins linebacker Zach Thomas still is questionable for Sunday's game due to a neck injury he suffered 2 1/2 weeks ago. Thomas missed the Dolphins' game in London against the New York Giants. He still is having headaches and has not been cleared for contact. He was participating in a limited way in practice Wednesday. Derrick Pope, a seventh-round pick in 2004, would start if Thomas can't play.
Dolphins veteran defensive tackle Vonnie Holliday did practice Wednesday and is expected to play for the first time in a month. He has been out with a hairline fracture of his ankle.
Miami has had a revolving door at safety. Renaldo Hill is out for the year with a knee injury. Travares Tillman has missed the last five games with a knee injury. Starting in their place are likely to be Cameron Worrell and Jason Allen.
