LITTLE ROCK, Ark. (KTHV) -- A big upset for the Hogs as they get the first loss of the season Saturday night at War Memorial Stadium in Little Rock.

The eighth-ranked University of Arkansas Razorbacks fell 34-31 in overtime against University of Louisiana-Monroe.

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. According to CBS Sports, Wilson's injury is a broken collarbone and would be out 3-4 weeks. CBS College Network, however, just released a statement saying that report has not been confirmed with Arkansas staff.

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.
