Clemson is No. 1, followed by Auburn, Oklahoma and Wisconsin in the last College Football Playoff rankings before the semifinals are set by the selection committee on Sunday.

Alabama fell from No. 1 to fifth in the new rankings Tuesday night after losing to Auburn, and Georgia was sixth. Miami slipped after taking its first loss of the season last week from No. 2 to seventh, just ahead of Ohio State at eighth.

Each of the top four teams plays a conference title game this Saturday against another highly ranked team, creating potential play-in playoff games. Clemson faces Miami in the Atlantic Coast Conference championship; Auburn and Georgia play for the Southeastern Conference title; Wisconsin faces Ohio State for the Big Ten title; and Oklahoma faces No. 11 TCU for the Big 12 title.

If the top four win out, the semifinals likely would fall into place: Clemson vs. Wisconsin and Auburn vs. Oklahoma.
