Quarterback Brandon Allen threw a 25-yard touchdown pass to wide receiver Drew Morgan on the first play of the fourth overtime and three straight Auburn incomplete passes on the ensuing possession Saturday gave Arkansas a wild, 54-46 win over the Tigers in Fayetteville, Ark.

Allen passed for 233 yards and three touchdowns for the Razorbacks (3-4, 2-2 in the SEC), who won for only the second time in their last six games.

Tailback Alex Collins ran for 105 yards and a touchdown before being injured late in regulation, but fullback Kody Walker ran for two of Arkansas' four overtime touchdowns, while Morgan finished with six receptions for 56 yards and two scores.

Tailback Peyton Barber rushed for 118 yards and four touchdowns, three in overtime, for Auburn (4-3, 1-3), which had won two straight in the series.

Wide receiver Jason Smith and backup quarterback Jeremy Johnson also ran for touchdowns for the Tigers, while freshman quarterback Sean White completed 19-of-32 passes for 254 yards.

The teams traded touchdowns in the first two overtime periods, with Barber scoring on a pair of two-yard runs for Auburn, and Arkansas countering with a six-yard pass on fourth down from Allen to wide receiver Drew Morgan and a three-yard run by fullback Kody Walker.

Auburn and Arkansas matched touchdowns and two-point conversions in the third overtime, with Barber scoring on a one-yard run followed by two-point conversion pass from White to wide receiver Melvin Ray for the Tigers.

Walker scored on a fourth-down, four-yard run on an option pitch and an Allen-to-tight end Jeremy Sprinkle two-point pass for Arkansas tied the score again.

Then, on the first play of the fourth overtime, Allen connected on an out route to Morgan, who shook free of an Auburn defensive back and sprinted down the sideline, diving for the final few yards to complete the scoring play.

Walker hauled in a rollout pass from Allen for the two-point conversion.

Barber gained a yard on Auburn's ensuing possession, but three straight incompletions by White followed to seal the Razorbacks' hard-fought home win.

After trailing 14-7 at halftime, the Tigers drove 75 yards on 13 plays on the opening possession of the third quarter and pulled even on a nine-yard scoring sweep by wide receiver Jason Smith.

The Razorbacks regrouped on the drive and capped the eight-play, 69-yard drive with tailback Alex Collins' seven-yard scoring run on a pitch play with 2:14 left in the third quarter.

However, Auburn answered with a 12-play, 93-yard march, highlighted by a 46-yard completion from White to Smith and culminated by a one-yard, fourth-down scoring plunge backup quarterback Jeremy Johnson with 6:54 remaining in the game.

With the game knotted 21-21, Arkansas took possession at its own 25 and methodically covered 68 yards in 13 plays to set up a 25-yard field goal by Cole Hedlund with 1:04 to play.

That proved to be four seconds too much, as White drove the Tigers to the Arkansas 24 -- thanks largely to 28- and 20-yard completions to wide receiver Ricardo Louis -- setting up Daniel Carlson's 41-yard field goal which sent the game to overtime with only four ticks left on the clock.
