AUBURN, Ala., Nov. 27 (UPI) -- Greg McElroy's late touchdown pass to Roy Upchurch helped third-ranked Alabama escape with a 26-21 win over bitter SEC arch-rival Auburn.
It was Alabama's second straight 11-0 regular season.
Trent Richardson's touchdown and McElroy's first scoring pass led to a 14-14 halftime tie, and Alabama won the second-half scoring battle 12-7.
Leigh Tiffin kicked two field goals and Colin Peek caught a touchdown pass among 53 receiving yards for the unbeaten Crimson Tide (12-0, 8-0), who face top-ranked Florida at the SEC title game Dec. 5.
Auburn's Chris Todd passed for 181 yards, two touchdowns and one interception.
Darvin Adams added a 72-yard, third-quarter touchdown catch for the Tigers (7-5, 3-5), who had won seven of the nine Iron Bowl games played at Auburn.
