Bombers defence dominates, Collaros tosses four TDs in 31-13 win over Riders

Linebacker Adam Bighill relished the way the Winnipeg Blue Bombers defence bounced back from their worst performance of the season. 

The defence forced six turnovers to key a 31-13 victory over the Saskatchewan Roughriders before a sold-out crowd of 33,234 fans at IG Field on Friday night. 

Winnipeg, which had given up 48 points in a loss to the Hamilton Tiger-Cats two weeks ago, 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.
