Both teams have played in one-score games (less than eight points) in each of the past four matchups. … The Dolphins enter the game in hopes of ending a two-game skid. Overall, Miami has lost six of its past eight games, including four of the past five. … The Bills enter the game on a two-game win streak. … Both starting quarterbacks made their returns last week after dealing with injuries. Miami’s Ryan Tannehill returned after five games to nurse a capsule injury in his right shoulder, while Buffalo rookie Josh Allen missed four games due to an elbow injury. … Sunday’s game marks the return of embattled defensive tackle Jordan Phillips, who was released by Miami in October and claimed one day later by Buffalo. … Dolphins tight end Nick O’Leary will also face his former team two months after the Bills waived him. … Both teams will wear throwback uniforms during the game, while select players will wear commemorative cleats to be auctioned for their respective charities in the My Cause, My Cleats initiative.
