"Buffalo Bills quarterback Trent Edwards is not progressing as fast in his recovery from a concussion as he did last season.

However, Edwards did participate in a limited part of practice Wednesday and expressed optimism that he will recover fully from the head injury he suffered against the New York Jets on Oct. 18.

"I feel 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. I've gotten better each day, and I'm happy with where things are at."

Edwards acknowledged he's not 100 percent healthy. But he would not discuss in detail the nature of headaches he has encountered since the injury. Is he still having after-effects?

"Not too much," he said. "Slowly but surely they're all kind of going away. I'm happy with the medical attention I'm getting and the training staff here."

After Edwards suffered a concussion last October, he was practicing fully and cleared to play by the 10th day after the injury. That's not the case this year. He already has been ruled out for Sunday. Coach Dick Jauron said Edwards won't be available in any capacity against Houston, even as a third quarterback.

Edwards said he is not concerned about the long-term effect of having two concussions in 12 months.

"It's the same as any other injury, for me at least," he said. "I faced the same situation last year. It's an injury, and once you get past it there isn't any looking back. And any time you look back it's not going to help you out. I'm going to be able to do that just like I did last year.""
