Orchard Park, NY - Buffalo Bills rookie wide receiver Sammy Watkins was listed as questionable for Sunday's game against the Kansas City Chiefs.

Watkins did not practice for a second straight day on Friday with a groin injury that forced him to leave Wednesday's session early.

The Bills' first-round pick leads the team in receptions (38), receiving yards (590) and touchdown catches (five).

Running back Fred Jackson (groin) was also listed as questionable on the club's injury report after being limited in practice this week.
