NEW YORK - Commence debate - the pairings are in, and Penn State and Michigan are out.

Alabama is the No. 1 seed in the College Football Playoff and will meet No. 4 Washington in a semifinal game at the Peach Bowl on Dec. 31.

The other semifinal is No. 2 Clemson against No. 3 Ohio State at the Fiesta Bowl, also Dec. 31.

Alabama is the only team to be in all three editions of the CFP so far. Ohio State and Clemson are in for the second time, and Washington is a first-timer in the four-team field.

Penn State finished No. 5 and is headed to the Rose Bowl. Michigan was No. 6, likely now bound for the Orange Bowl.
