The 11-3 AFC West-leading Broncos have already sewn up the division title - having beaten the second-place San Diego Chargers (9-6) twice this season - but Peyton Manning et al. need a win to secure a first-round bye, and seek to surpass the 11-3 New England Patriots to earn the AFC's top seed and home field advantage through the playoffs.
The 9-4-1 Bengals, on the other hand, are in the middle of a dogfight for the AFC North; they hold the tiebreaker over the 9-6 Baltimore Ravens after winning both games against their divisional rival this season, but lost 42-21 at home to the 10-5 Pittsburgh Steelers two weeks ago thanks to a very solid 350 yards passing from Ben Roethlisberger and an even more solid 185 yards on the ground from Le'Veon Bell.
The Bengals finish the season on Sunday away to the Steelers, who are already assured of postseason action, so it could come right down to the wire for Andy Dalton and company if they lose tonight.
Have fun, be good for goodness' sake!
