Bills QB Trent Edwards (concussion) took part in individual work at practice Wednesday. He has already been ruled out for Sunday's game against Houston, and Ryan Fitzpatrick will start against the Texans. "I'm good," Edwards said. "It's good to be back here. I wasn't here last week, and it was kind of lonely at the house. But I feel a lot better." Edwards said he is not currently worried about losing his starting job. "Honestly, that's not on the top of my mind right now," he said. "I have a lot to think about in terms of just getting healthy and trying to help the team win." Edwards said the after effects from his concussion are pretty much gone. "Slowly but surely they’re all kind of going away," he said.
