It didn’t take long to deliver the first big upset of the season in college football.

The Louisiana Rajun Cajuns took down No. 23 Iowa State, 31-14, which had drawn some attention from college football experts and analysts as a dark horse contender to make noise in the Big 12 and even reach College Football Playoff. For good measure, the Rajun Cajuns had a punishing double-digit play drive to run the clock out late, and scored with 10 seconds remaining. It was the first ever road win against a ranked team for Louisiana.

At halftime, Iowa State had a narrow 14-10 lead.

But the Rajun Cajuns delivered two big plays in the second half to build a double-digit lead on the road. The first was a 78-yard pass from Levi Lewis to Peter LeBlanc as the Rajun Cajuns grabbed the lead for the first time in the game. Then Louisiana delivered an 83-yard punt return by Eric Garror early in the fourth quarter.

The box score was largely even except for turnovers, where Iowa State had two, a fumble and interception.
