ORCHARD PARK, N.Y. -- Buffalo Bills receiver Sammy Watkins' status is uncertain for Sunday's game against the New York Giants because of a calf injury.

Coach Rex Ryan provided an update on Monday, a day after Watkins left in the first quarter of the Bills' 41-14 win at Miami.

Ryan said "it's a possibility" Watkins won't be available this week. Bills players had Monday off.
