The Buffalo Bills lined up in the Wildcat formation five times and netted a negative 11 yards in Sunday's game against the Kansas City Chiefs.

The formation is a work in progress, Bills coach Chan Gailey said Wednesday.

"The Wildcat looked like it was the first time we'd run it in a game, that's what it looked like," Gailey said. "It's got rust all over it, and we've got to polish it up, get it ready to go in the future. And we're going to continue to use it as many weeks as we see it being a viable part of our offense. So you're going to see it some more. We've got to add some stuff to it, we've got to put in a few more things. But I like where we're heading with it."

The Bills didn't use the Wildcat in the season opener because option quarterback Brad Smith was nursing a sore groin. Smith had two positive plays out of the Wildcat versus the Chiefs, handing to C.J. Spiiler for 7 yards on a second-and-5 situation and gaining 5 yards on a first-and-10 play. However, the Bills also lost 15 yards on a muffed handoff on a Wildcat snap. They gained 2 yards on a direct snap to Tashard Choice. A fifth Wildcat play was wiped out by a holding penalty on the Bills.


Bills safety Jairus Byrd sat out Wednesday's practice with an ankle injury. Byrd was walking around without a boot on the foot but Gailey said it may be Sunday before the team would know if he can play.

"He's taken a step back," Gailey said. "He's going to struggle to make some practice this week, so we'll have to see. It may be a game-time decision on him."

Receiver Ruvell Martin (ankle) also sat out. Defensive tackle Marcell Dareus was in Alabama attending the funeral of his slain younger brother.

The Browns will be without their best cornerback, Joe Haden, who is serving a four-game suspension for violating the NFL's substance abuse policy. Cleveland was mostly healthy in practice Wednesday. Dynamic kick returner Joshua Cribbs was limited with a knee injury. Starting defensive tackle Billy Winn sat out due to a concussion.


Gailey resisted the invitation to jump on the bandwagon and criticize the replacement referees.

"Yeah, there's some differences, sure there is. But like I said, we complain about them all. That's just coaches' nature, it doesn't matter who they are. They're human. They don't get it all right," Gailey said. "We've had two games and they have not determined the outcome of either game. That's all I can comment on. I think for the most part players play and coaches coach and referees do their job and they're doing the best they can."


Gailey did take a shot at his own play-calling, for the reverse run by Dorin Dickerson that lost 8 yards vs. Kansas City.

Asked about the keys to the Bills' success in the red zone, Gailey said: "Well, one of them's not running a reverse on the 2-yard line and losing 8 yards so we can throw a 10-yard touchdown pass. I don't believe that's one of the keys."
