(TSX / STATS) -- ROCHESTER, N.Y. -- Two key offensive players opened camp on a "rep count" as the Buffalo Bills took to the field Thursday night on the campus of St. John Fisher College.

Wide receiver Sammy Watkins and offensive left tackle Cordy Glenn missed significant time in the offseason. Watkins was rehabbing following his second foot surgery, and Glenn was out with a troublesome ankle injury. But both were on the field when the workout began in front of an energetic opening-night crowd.

Coach Sean McDermott said the team would monitor and manage the workload for both players.
