ORCHARD PARK, N.Y. -- The Buffalo Bills returned to practice Monday following their bye week. More importantly, so did their starting quarterback.
Trent Edwards was back at work a week after being knocked out in Buffalo's Week 5 loss to the Arizona Cardinals and said he expects to play Sunday
when the Bills (4-1) host the San Diego Chargers (3-3) in a key AFC matchup.
"I'm getting better each day," he said of the concussion. "It was a tough couple of days there after the hit. I had some headaches and residual effects from it, but slowly but surely they're going away."
Edwards is scheduled for more tests Tuesday but he's confident everything will be fine.
"If those [results] come back the way I think they're going to come back, we should be good to go on Sunday," he said.
After consulting with team physicians Monday morning, he was cleared for a full practice.
"The doctors and trainers were pleased with my progress, and I'm feeling better and healthier each day," Edwards said.
Edwards was knocked cold on the third play from scrimmage when Cardinals strong safety Adrian Wilson drove him to the ground. Edwards missed both practices last week before the Bills began a four-day layoff on Thursday and said his headaches began to dissipate over the weekend.
Edwards didn't want to comment on the hit or the $25,000 fine the league levied against Wilson but admitted he has no memory of the 10- to 15-minute span that immediately followed the play.
"I remember sitting in the trainers room with my pads off and my shoes off, but I don't remember how I got to the training room or who hit me," he said. "I was kind of out of it and didn't know where I was. Slowly I came back to it."
Edwards has gone 81-of-122 for 948 yards with four touchdowns and two interceptions in just over four games. He's been solid in the fourth quarter as well, with a combined 24-of-32 for 334 yards with two touchdowns in helping Buffalo rally from three consecutive fourth-quarter deficits this season.
"It was good to see him back smiling, feeling good and being able to come out there and make some plays," receiver Lee Evans said. "It's good to get him back in the swing of things."
Receiver/punt returner Roscoe Parrish practiced for the first time since surgery to repair ligament damage in his right thumb that forced him to miss the past two games. Starting free safety Ko Simpson also practiced. He missed the second half of the Cardinals game because of a hamstring injury.
Both players said they should be ready for Sunday's game, but Parrish's situation will be monitored more closely as the week goes on.
Starting cornerback Terrence McGee and starting defensive end Aaron Schobel both missed Monday's practice. McGee sprained his left knee early against the St. Louis Rams in Week 4 and missed the Cardinals game, while Schobel is nursing a nagging left foot injury.
