Lewis Central (8-2) scored the first points in two quarters on a 39-yard touchdown pass from Austin Simmons to Luke Harrison with just two minutes remaining in Wednesday's game.
A crucial pass interference penalty was called several minutes earlier that kept the drive alive for the Titans. Le Mars (7-3) would have been able to take over on offense in a tie game with five minutes left to play.
"I thought it was a great play by (Jeremy) Singer," said Le Mars head coach Gabe Tardive.
The Bulldogs drove the ball into Lewis Central territory, as they did for much of the night, on the ensuing possession.
A final pass attempt into the end zone with seconds left on the clock was intercepted by Lewis Central. It was the third interception for Le Mars and a fourth turnover overall. Le Mars was also called for eight penalties for 72 yards, while Lewis Central was penalized just three times for 20 yards and turned the ball over just once.
"We made mistakes and we made turnovers that cost us, but we fought and we battled," Tardive said. "The kids, I've got to give them all of the credit in the world. They just keep fighting. We have a bunch of fighters."
Lewis Central had the upper-hand early on with two passing touchdowns in the first quarter. Simmons first found Harrison for a 29-yard touchdown pass. Caleb Shudak kicked the extra point at the Titans led 7-0.
Le Mars responded in the second quarter on a 20-yard touchdown pass from junior Levi Te Brink to senior Jeremy Singer. The Bulldogs trailed 14-6.
Senior running back Travis Kinney scored on a 10-yard touchdown run later in the second quarter. Te Brink ran in for the 2-point conversion to tie the game at 14-14.
The game would remain deadlocked until the decisive score in the fourth quarter, despite plenty of yards put up by both offenses.
Le Mars out-gained Lewis Central 377-291 in offensive yardage. Le Mars was 7-for-14 on third downs and held Lewis Central to 3-for-11 on third downs and 1-for-2 on fourth downs.
Te Brink finished 9-for-26 passing for 133 yards, one touchdown and three interceptions. Te Brink gained 122 yards on the ground on 15 carries.
Senior Kendall Candor ran 11 times for 66 yards. Kinney scored once and gained 53 yards on 13 rushing attempts.
Senior Gabe Rahn caught three passes for 61 yards. Senior Joey Husk caught three passes for 23 yards. Singer, senior Brennan Buss and junior Chris Hatting each caught one pass for 20, 13 and six yards, respectively.
Buss made six solo stops. Hatting made four solo tackles, assisted on two more and made a sack.
Le Mars was led by a group of seniors that also included Conner Delfs, David Lamp and Matt Strub as the team improved to 7-3 after going 1-8 in 2011.
"Hopefully we've laid the foundation for a program that is going to continue to improve," Tardive said. "I can't even describe the feelings I have for these seniors and what they've done for me and this program.
"I hate for it to end. You've got to give them all of the credit in the world. They fought and they battled. To have the opportunity to play at home -- they deserve all of the credit that they get. They've really set the foundation for us to do some special things here. We've just got to keep it going."
