AUBURN, Ala. -- The second-highest scoring Iron Bowl in series history was a thriller from start to finish, but it was a missed 30-yard field goal with 2 minutes remaining that doomed No. 5 Alabama as it lost 48-45 on the road at Jordan-Hare Stadium to No. 15 Auburn. The Tigers, which faced an exceedingly tough schedule this year, ended the regular season with a signature win for coach Gus Malzahn and Co. 

Auburn took a 40-38 lead into the fourth quarter and held on for a three-point win, forcing Alabama to go for it on fourth down late in the game and then seeing its rival miss a 30-yard field goal after initially facing first-and-goal from the 10-yard line. After getting the ball back, the Tigers appeared to be headed toward a three-and-out, but Malzahn kept his offense on the field on fourth down and tricked the Crimson Tide into an illegal substitution, giving the ball back to Auburn to run out the clock.

Auburn's offense did not put up gaudy stats with quarterback Bo Nix completing 15 of 30 passes for 173 yards and a touchdown. In fact, no receiver had more than 66 yards, though running back JaTarvious Whitlow picked up 114 yards on 16 carries. However, the Tigers defense capitalized on two huge mistakes by Tide QB Mac Jones, who threw a pair of pick sixes as the team's starter in for injured Tua Tagovailoa, including the longest in Iron Bowl history.

Jones was otherwise fantastic, completing 26 of 39 passes for 335 yards and four touchdowns, three of which went to Jaylen Waddle, who had 98 yards on four receptions. Waddle also added a 98-yard kickoff return touchdown, giving him four scores in the game, which doubled his season total. Najee Harris was also tremendous for Alabama's offense, adding 146 rushing yards and a touchdown on 27 carries.

Alabama outgained Auburn 515-354, matching the hosts on the ground but besting the Tigers through the air 335-173. However, the Tide did not have a single sack in the game and only had four tackles for loss. Though the score may not show it, Auburn beat Alabama with defense, which is how the Tide have been so dominant historically.
