ORCHARD PARK, N.Y. (AP) — The Buffalo Bills' offseason-long quarterback competition is down to two players now that AJ McCarron is seeking a second opinion to determine the severity of an injury to his throwing shoulder.

Coach Sean McDermott on Sunday declined to reveal many details on McCarron's status except to say the team is still evaluating the injury after initial tests were inconclusive.

And yet McDermott acknowledged the injury will have an immediate effect on McCarron's place in the quarterback pecking order with rookie first-round pick Josh Allen and returning backup Nathan Peterman still competing for the starting job.

McCarron took several hits and was hurt during the first quarter of Buffalo's 19-17 preseason win at Cleveland on Friday.

The Bills avoided a major scare on another injury front.

Defensive tackle and team leader Kyle Williams is listed week to week after the 13-year veteran hurt his right knee early in the second quarter against the Browns.
