ORCHARD PARK, N.Y. (AP) -- Bills safety Aaron Williams has been ruled out for Sunday's game against the Miami Dolphins due to a rib injury.
Williams was hurt in Buffalo's win Sunday over the Jacksonville Jaguars and did not practice all week. Veteran Jim Leonhard is expected to start in his place. Williams has been a pleasant surprise for the Bills this season ever since making the switch from cornerback to safety. He is second on the team in tackles with 82 and has four interceptions.
Wide receiver Stevie Johnson was also officially ruled out. Johnson has been excused from practice this week following the death of his mother.
Quarterback EJ Manuel (knee) was ruled out earlier in the week. Thad Lewis will start at QB for the Bills.
