There are 4 remaining combos for the AFC Divisional playoffs:
HOU-BAL/ KC-BUF
MIA-BAL / HOU-BUF
HOU-KC / PIT-BAL
MIA-HOU / PIT-BAL
Since we know the PIT-BUF winner will play Sunday of divisional weekend, that guarantees that if Miami wins tonight, they would definitely play Saturday. Kansas City could go either way. m Houston has a 3 in 4 chance of playing Saturday. They would need Miami and Buffalo to win, in which case they'd play Sunday.
