Watkins (ribs) practices Wednesday

ORCHARD PARK, N.Y. -- Buffalo Bills wide receiver Sammy Watkins practiced Wednesday in advance of the team's regular-season opener Sunday in Chicago.

The Bills will release their first injury report Wednesday afternoon that will list Watkins' status in practice -- either limited or full participation.

Meanwhile, tight end Lee Smith (toe) was the only player not practicing Wednesday.

If Smith can't play Sunday, expect Scott Chandler and Chris Gragg to see the majority of snaps at tight end.
