Montreal Carabins upset No. 1 Laval Rouge et Or in Week 4 of U Sports football

The top team in U Sports football weekly rankings fell to their rivals this week, as the latest round of Canadian university football did everything it could to keep fans on the edge of their seats in the fourth week of an electrifying season.

The Laval University Rouge et Or came into Week 4 as the No. 1 team in the U Sports top-10 rankings, but they didn't look like their usual selves in a 31-14 loss to the visiting University of Montreal Carabins on Sunday.

In front of over 18,000 fans in Quebec City, Laval committed six turnovers, including three fumbles and three interceptions — Montreal's Bruno Lagace caught two of those and Guillaume Perrier's pick-six broke the 14-14 tie with seven minutes remaining. The Carabins capitalized on the Rouge et Or's misfortune, scoring 22 unanswered points in the second half to bring down the defending Vanier Cup champions.

"It's an exceptional piece of execution," said assistant defensive coordinator Antoine Pruneau after the road win. "The guys were physical and it's been a long time since we've seen energy like that."
