Orchard Park, NY (Sports Network) - Buffalo Bills wide receiver Stevie Johnson is active for Sunday's game against St. Louis after being questionable with a hamstring injury.

Johnson was hurt last week against Jacksonville and practiced on a limited basis Thursday and Friday after missing Wednesday's session.

He leads the team with 55 catches for 705 yards and five touchdowns.

Cornerback Aaron Williams won't play Sunday because of a knee injury, while the Bills had already ruled out defensive end Mark Anderson and center Eric Wood because of knee issues.
