Adam Lowry helped make sure Edmonton failed to set a new franchise best winning streak.
The Swift Current winger scored twice and Eetu Laurikainen turned aside 38 of 39 shots to lead the Broncos to an upset 3-1 win over the visiting Oil Kings in Western Hockey League action Sunday.
Edmonton (41-12-5) was going for a record 12th straight win, but came up against a plucky Broncos team that jumped out to an early lead.
Lowry scored his team leading 35th goal to give the Broncos a 1-0 first period lead. He added his 36th of the year on a power play just 45 seconds into the third period.
Broncos defenceman Reece Scarlett had three points after assisting on each Swift Current goal.
Elsewhere in the WHL, it was: Kelowna 3 Everett 2; Medicine Hat 3 Kootenay 2; and Victoria 5 Spokane 3.
