Zach DuBois answered Ayers' TD with an impressive 42-yard, tackle breaking score of his own. However, the Lancers missed the PAT and still trailed 19-18 midway through the 4th.
The Bulldogs added to their lead with a halfback option scoring pass. Derek Bishopp hit Josh Wester on a 19 yard play. Bishopp also scored each of Livonia's first two touchdowns.
Elba/B-B had two chances to tie, but both times Struble intercepted a long pass near midfield. Bishopp also picked off a pass early in the fourth.
