Bills' Lynch limited by back spasms; Edwards a game-time decision

ORCHARD PARK, N.Y. -- Severe back spasms limited Marshawn Lynch in practice Thursday, though Bills coach Dick Jauron was confident the running back will play against Miami this weekend.

Lynch's back locked up during individual drills early in practice. After spending about 10 minutes trying to stretch himself out while being attended to by a trainer, Lynch returned to practice, but still had severe difficulty bending over. He had particular trouble picking up a ball after he dropped a pass.

Jauron dismissed worries about Lynch's status, noting the team's leading rusher has played through back spasms in the past.

The Bills (6-6), who have lost five of their past six, host the Dolphins (7-5) in playing their first of five annual regular-season games at Toronto's Rogers Centre on Sunday.

Quarterback Trent Edwards (groin) missed practice for a second straight day, and his status remains uncertain since he was sidelined by the injury after the first half of a 10-3 loss to San Francisco last weekend. Edwards is expected to be a game-time decision.

Defensive Aaron Schobel remains a possibility to play after the team's leading pass rusher practiced fully for the second straight day since missing seven games with a left foot injury.
