Cole Tennant led the Burgher ground game with 53 yards, and the normally productive Jason Power was held to 11 yards, as was talented teammate Mike Perrone.
Versatile quarterback Brendan Frye picked up 39 yards on the ground, and connected with Perrone on an 11-yard pass play for a touchdown.
Leonbruno offered comments for two of his players, Power and Kendall Converse. The coach said Power has been playing well all season, and Converse stepped up on defense, making key tackles for the Burghers.
The Bishop Gibbons game was the fourth loss after a solid, promising start to the season.
The prior week's loss, however, a 28-21 defeat by Hoosic Valley, was nearly a win for Warrensburg - Hoosic Valley turned the tide in the last several seconds.
Monday, Leonbruno was ever hopeful his players would dig deep and summon up the spirit of past Warrensburg players, like Nate and Mike Monforte, Mason Hamilton, Chris Cameron, Bobby and Brad West, Joe Guistino, Matt Blair, Dave Mahler, Ryan Winslow, Jon Alexander, John Welch, or Darrin Rafferty.
"If we come out strong, get an early lead and keep up the momentum, we've got a shot in the Sectionals," he said. "If we play for a whole game believing we can win, we'll do it."
