The New England Patriots and Pittsburgh Steelers are both in the AFC Championship Game after their 34-31 overtime victory over the Kansas City Chiefs.
But the Patriots are playing on Thursday night in a rematch of the AFC championship game, while the Steelers are facing off against the Indianapolis Colts in their final game of the regular season.
The Patriots are 4-0, while Pittsburgh is 4-2.
The AFC championship is the only game between the teams that has a winner-take-all tiebreaker.
The Colts won that tiebreaker over the Patriots in Week 1, but the Patriots beat them by a combined score of 41-3.
