FAYETTEVILLE, Ark. (AP) - Brandon Allen threw a 25-yard touchdown pass to Drew Morgan on the first play of the fourth overtime, also converting on the 2-point conversion, to lead Arkansas to a 54-46 win over Auburn on Saturday.

The win is the first for the Razorbacks (3-4, 2-2 Southeastern Conference) over former offensive coordinator and current Tigers coach Gus Malzahn in three games, and it keeps Arkansas' bowl hopes alive.

Alex Collins rushed for 105 yards and a touchdown on 25 carries to lead Arkansas, topping 100 yards rushing for the fourth time in five games.

Sean White was 19-of-32 passing for 254 yards for Auburn (4-3, 1-3), which had its two-game winning streak snapped.

The game is the longest in major college football this season, according to STATS.
