The Cincinnati Bengals will wear white jerseys, white pants, and black socks when they face the Buffalo Bills in the AFC Divisional round.
The Bengals are 3-0 in that combo, having beaten the Tampa Bay Buccaneers in Week 15, the Tennessee Titans in Week 12, and the New Orleans Saints in Week 6 while wearing it.
Though it is now being reported that there will be light snow flurries in Orchard Park come game time, there is no indication that the white combo is intended to obscure Bengals players from the sight of their opponents, as this scheme would likely not be effective; orange helmets are pretty easy to spot.
