Kolton Browning's 16-yard touchdown run on fourth-and-one lifted Louisiana-Monroe to a 34-31 overtime win over No. 8 Arkansas.
Browning accounted for 481 yards of total offense and four touchdowns to lead the Warhawks (1-0) to their first win over a Southeastern Conference team since defeating Alabama in 2007.
The Razorbacks (1-1) played the second half without quarterback Tyler Wilson, who suffered a head injury after taking several big hits in the first half.
Wilson, who also missed the second half against New Mexico last season with concussion-like symptoms, was 11-of-20 passing for 196 yards and a pair of touchdowns before leaving the game at halftime.
Louisiana-Monroe outgained Arkansas 550-377 in total yards.
