Coming off their worst performance of the season, the Winnipeg Blue Bombers defence forced six turnovers to lead the way in a 31-13 victory over the Saskatchewan Roughriders before a sold-out crowd of 33,234 fans at IG Field.
Winnipeg, which had given up 48 points to the Hamilton Tiger-Cats last week in a loss, forced three turnovers on downs, a fumble and grabbed two interceptions to improve to 13-2 and clinch a home playoff game in the West.
Winnipeg quarterback Zach Collaros completed 14-of-25 passes for 296 yards and four touchdowns. Kicker Marc Liegghio hit all four extra-point attempts and added a 22-yard field goal.
Saskatchewan falls to 6-9 but remains in the playoff picture. Riders quarterback Cody Fajardo completed 26-of-38 passes for 307 yards and one interception.
