Alabama, Ohio State, Michigan and Clemson held the top four spots in the College Football Playoff rankings for the second straight week and Washington moved up a spot to fifth this week.

Wisconsin is sixth in the selection committee rankings released Tuesday night. Louisville was the team that took a big drop. The Cardinals fell from fifth to 11th after losing at Houston.

Ohio State and Michigan play Saturday in Columbus, Ohio, and the loser is likely to be out of the playoff race. The Wolverines would move on the Big Ten championship game by beating the Buckeyes. The Buckeyes, though, need help to reach the conference title game.

Unbeaten Alabama meets Auburn on Saturday, but the Crimson Tide has already clinched a spot in the SEC title game.
