Both goals were tough to swallow, with Watson's basically coming on shorthanded breakaway (time on Lethbridge's penalty expired just as the puck entered the net) and Leverton stuffing home a loose puck after Brandon goaltender Corbin Boes mishandled an easy dump-in in the crease area.
"Going into the third period, it's a 0-0 game, basically, going into the third period and it's up for grabs," said Brandon coach Dwayne Gylywoychuk on CKLQ's post-game show, "They came out and scored two bang-bang goals on plays that just shouldn't have happened, and from there it was the game."
Alessio Bertaggia and Jayce Hawryluk scored in the first period for the Wheat Kings as Brandon jumped out to a 2-0 lead after 20 minutes for the second straight game.
Jay Merkley and Russell Maxwell scored in the second period to tie it for Lethbridge, although both goals were preventable in Gylywoychuk's eyes.
"We made a mistake in the neutral zone, got on the wrong side of a check and the puck was in our net," said Gylywoychuk, "We have a chance on our penalty-kill to ice the puck, we had the puck on our stick and no one around us and we don't get the puck out and it's in our net."
Geordie Maguire also scored for the Wheat Kings, the first of his Western Hockey League career that briefly made it a 4-3 game with just under six minutes to play.
"It's a bittersweet goal. I saw the defenceman bobbling it and I got past him and ended up all alone on the goalie and knew exactly where I wanted to put it," said Maguire, "I got the monkey off my back. I wish it could have happened in a better game but I'm happy in a better game but I'm happy I scored it."
However, Macoy Erkamps scored less than two minutes later to restore the Hurricanes two-goal advantage.
Former Wheat King Ty Rimmer made 35 saves for the win in his first start back in Brandon since being traded by the Wheat Kings in October of 2010.
Corbin Boes stopped 28 shots in a losing cause for Brandon, who fell to 9-8-2-1 with the loss.
The Wheat Kings will close out their five-game home stand by hosting the Swift Current Broncos on Sunday (5:05 p.m., Westman Communications Group Place).
