Bills coach Sean McDermott said veteran defensive lineman Kyle Williams will be considered week-to-week with a knee injury suffered in Friday night's preseason game against the Cleveland Browns.
McDermott said early indications are that Williams does not need surgery.
Third-round rookie Harrison Phillips is expected to fill in for Williams.
McDermott also said quarterback AJ McCarron is receiving a second opinion on his injured right shoulder because initial tests are "not totally conclusive." McCarron suffered a hairline fracture in his right collarbone, The Buffalo News reported Friday.
McDermott said that if healthy, McCarron is still in the QB competition and "we pick up where we left off." He wouldn't comment on how the injury affects the competition among McCarron, Nathan Peterman and rookie Josh Allen.
McDermott said it is not an ideal situation for McCarron to miss time, but he also said the coaching staff has a pretty good idea of what he is capable of doing.
As for Allen's performance, McDermott said, “I thought he moved the ball and generated points in all three drives. That was good to see. Each opportunity is a good experience. I thought he had good command of the offense.”
But, McDermott cautioned, the Bills need to "manage expectations" despite the excitement among the fan base about Allen.
As expected, punter Cory Carter is out for the season after tearing an ACL during Friday's game. He was waived/injured Sunday. Carter was signed to the Bills' practice squad late last season.
Also, Trent Murphy remains day-to-day with a groin injury. He again said Murphy and the medical staff are "working through it."
