ORCHARD PARK, N.Y. -- Right guard Brad Butler and defensive end Aaron Schobel won't play Sunday for Buffalo, leaving the AFC East-leading Bills without two key starting linemen for their game at Miami.
Butler sprained his left knee in the first half of Buffalo's win over San Diego this past week, while Schobel is still hobbled by ligament and bone injuries to his left foot. Schobel has been walking with a protective boot and hasn't practiced since aggravating the injury during a 41-17 loss at Arizona on Oct. 5.
Schobel missed the Chargers game, snapping a string of 117 straight appearances since he entered the league in 2001.
Nickel back Ashton Youboty (foot), starting center Melvin Fowler (elbow), and cornerback Terrence McGee (left knee sprain) are all questionable. Fowler didn't play against the Chargers, while McGee has missed the past two games.
The Bills have a chance to go 6-1 for the first time since 1993, when they began 7-1 en route to their fourth consecutive Super Bowl appearance.
