Don Matthews pulled a fast one in the final minute of the second quarter that helped his Montreal Alouettes take a half-time lead.
It ended up being the turning point in Montreal's 44-16 triumph.
With the Winnipeg Blue Bombers leading 15-9, Als defensive back Clint Kent lined up behind punter Damon Duval on a punt and raced down the field to try to recover the onside kick.
The Als got a big break when the ball took a big hop backwards, allowing Kent to nab the pigskin just before it bounced out of bounds at Winnipeg's 29-yard line.
"That was going to be our ball, and that was a big play," said Bombers head coach Doug Berry.
Added Matthews: "It probably was a pretty big factor because it's right before the half."
Matthews credited special teams co-ordinator Noel Thorpe for drawing up the play.
Berry could see the play developing from the sideline, but he couldn't yell loud enough to prevent it from ending badly for his squad.
"We could see it developing, but it's just one of those things you don't practise every day," said Berry.
Five plays later, Als fullback Mike Vilimek rumbled into the end zone from a yard out to give Montreal a 16-15 lead at the break.
They never looked back.
INSPIRING RIDE: Chad Faurschou, a 20-year-old who was seriously injured in a car crash nine years ago, completed his bike-a-thon last night.
The Portage la Prairie resident, who suffered massive head trauma in the accident, rode his custom-built bike from his hometown to centre field at Canad Inns Stadium to raise money for the Movement Centre.
Faurschou received a rousing ovation from the crowd when presented with a special game ball just prior to kickoff.
FAMILIAR FACE: Former Bombers punter Jon Ryan, now with the NFL's Green Bay Packers, was on the Winnipeg sideline last night.
