Meanwhile, Drew Willy stepped in for Darian Durant and helped the Roughriders defeat the Hamilton Tiger-Cats 32-20.

Both teams have Week 6 byes.

The longtime rivals met in Week 2 in Regina, with Calgary holding the advantage in the first half before Saskatchewan rallied for a 36-21 win.

Friday also marks the Stampeders’ Purolator Tackle Hunger game in benefit of the Calgary Food Bank. Thanks to the overwhelming generosity of Stamps fans, a record total of 131,500 pounds of food was collected a year ago.
