Bills' McKelvin Game-Time Decision
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.
