A late defensive stand on a two-point conversion for South Beauregard proved to be the difference in a low-scoring contest.
With two minutes to go, Iowa attempted for 2 to tie it up, but the Knight defense sniffed it out to hold on for a 15-13 win over the Yellowjackets.
"It was huge," South Beauregard head coach Dwight Hudler said. "Now, it gives you that cushion so you don't have to go out and score. You still want to be aggressive and we were able to run the clock out and punt the ball away with a few seconds left. We covered well and tackled him with no time left."
The Knights jumped out to a 15-0 lead in the first behind a pair of passing touchdowns from quarterback Kyler Kibodeaux – a 79 yarder to running back Colby Hollier and a 15-yard pass to Iverson Robinson.
"It's no secret that we're going to try and run the ball," Hudler said. "We widened out Colby in the slot, and they didn't cover him. If you're going to let us get a free throw to him, we're going to take it. The second one, we have been working on it the last couple of weeks and never got a chance to get it off. We had good protection and the time was right. (Kyler) made a good throw, and Robinson made a good catch. It was great execution."
Iowa (2-5, 2-2) got on the board in the third quarter on a 90-yard pass to make it 15-7 and ran in a touchdown in the fourth to close the gap.
The win puts South Beauregard at 3-4 on the year and 1-2 in district play with three games to go.
"It's our first district win, so that's a big deal for us," Hudler said. "We're trying hard to fight to get into the playoffs. We told the boys that it is going to take four wins to get in. I know that's important to them. This is a big step for that.
"Iowa has been at the top of the district for the last couple of years. We seem to, for the most part, always play them pretty close. Even this year, I don't think they've lost a game by more than 10 points. We knew coming in it was going to be a dogfight."
Kibodeaux was 4-for-5 for 106 yards, and Jayden Derouen paced the Knights on the ground with 76 yards on 21 carries.
Chandler Rutherford led the defense with 12 tackles and an interception.
South Beauregard hosts Washington-Marion next week at 7 p.m.
"We've been telling the boys all year that we are close to being a really solid team," Hudler said. "I think they're starting to believe that. We still have some things we need to clean up. Offensively, our mistakes have been self-inflicted. In the second half, we had five holding penalties and two false starts.
"We had an interception last night on defense, and on offense, we have been taking care of the ball well. We haven't had a turnover in the last four weeks."
