Kyle Williams' return from injury up in air

ORCHARD PARK, N.Y. -- Bills starting defensive tackle Kyle Williams has already been ruled out from Buffalo's next game, which isn't for another 10 days. And there's no telling when -- or if -- his nagging left foot injury will heal this season.

Coach Chan Gailey provided few definitive answers in updating Williams' status on Wednesday following Buffalo's final practice before entering its bye weekend.

Gailey said Williams will miss at least the next game, and perhaps another before having his foot re-examined. Without disclosing the exact nature of the injury, Gailey noted it's one that will bother the player for the rest of the season.

"I don't know if he'll be 100 percent for the whole year, I don't know if he'll make that," Gailey said.

The Bills (4-2) are off until "hosting" the Washington Redskins in their annual home game in Toronto on Oct. 30.

Williams has been bothered by the injury for much of this season, and aggravated it during a 31-24 win over Philadelphia two weeks ago. He then did not play in a 27-24 loss at the New York Giants last weekend.

The injury is so severe that trainers had previously cut out holes in the back of Williams' cleats to alleviate the pressure.

On Wednesday, Williams declined comment as he walked around the Bills' facility wearing a protective boot on his left foot.

Williams is coming off his first Pro Bowl appearance and has been the defense's most consistent player since earning a starting job as a rookie in 2006. Prior to this season, he's missed only two games.

The Bills have lost two of three since a 3-0 start, and could use a week off to allow a banged-up roster time to recuperate.

Starting linebackers Shawne Merriman (right Achilles tendon) and Nick Barnett (right ankle) were held out of practice Wednesday. Merriman did not play last weekend, but is confident he'll be back next week.

On the bright side, veteran LB Chris Kelsay took the field for the first time since missing two games with a left calf injury. Kelsay is confident he'll return to play against Washington.

Buffalo is depleted at left tackle, with rookie Chris Hairston expected to miss between two and four weeks with a right ankle injury. Hairston was starting in place of Demetrius Bell, who's missed two games with a shoulder injury. Bell has an outside shot of returning next week.

Receiver Donald Jones, who took over the No. 2 role, is expected to miss at least one more game since spraining his left ankle two weeks ago.

"There's no set target date yet," said Jones, who was initially projected to miss up to six weeks. "It's moving a lot faster than expected, but they don't want to rush it and have me come back too fast."
