Alabama is one of just four undefeated teams left in the country. Auburn took a big jump in the College Football Playoff rankings in Week 12 after knocking off then-No. 1 Georgia, which was previously undefeated. The winner of this year's Iron Bowl will win the SEC West and clinch a spot in the SEC Championship.

GameDay last went to Auburn in 2013, when the Tigers beat Alabama on the Kick Six as Chris Davis returned a missed field goal 108 yards after time had expired.
