Bills' Roscoe Parrish injures left leg

PITTSFORD, N.Y. -- Buffalo Bills wide receiver Roscoe Parrish left practice Wednesday night after an apparent leg injury and was ruled out of the team's first preseason game this Saturday in Chicago.

Parrish was running a fly pattern during a full-field drill when he came up limping and grabbing his left leg. Buffalo Bills head coach Chan Gailey expects him to miss extended practice time.

Defensive tackle Torell Troup had his right hand wrapped in a cast and did not participate in practice. Gailey did not specify the injury but expects Troup to practice with the cast after the swelling goes down. Gailey said Troup is questionable for Saturday.

The Bills lost another receiver when Craig Davis left practice after losing his wind, according to Gailey. The coach said Davis is expected to be fine.
