Buffalo Bills cornerback Leodis McKelvin will be a game-time decision Sunday against Baltimore because of a hamstring injury.
McKelvin, the Bills' No. 1 cornerback role with Stephon Gilmore (wrist) out, was injured in Buffalo's loss last week to the New York Jets. He was limited at practice on Friday.
If McKelvin is unable to play, safety Aaron Williams is expected to start at corner. Williams, a converted cornerback, went back to the position after McKelvin was injured.
Safety Jairus Byrd (plantar fasciitis) is questionable for the second week in a row. The standout safety has yet to play after missing all of training camp before signing his franchise tender.
Gilmore (wrist), cornerback Ron Brooks (foot), wide receiver Marquise Goodwin (hand) and kicker Dustin Hopkins (groin) are out.
