One “50-50” injury is good to go while another is a game-time decision for the Saskatchewan Roughriders Friday in Edmonton.

Veteran centre Dan Clark and his ankle “owie” have been given the green light to play while receiver Duke Williams is a game-time decision as to whether he’ll suit up for his third contest with the Green and White because of a hamstring issue. Otherwise, the Riders have two line-up changes from last week in Montreal. Import pass-catcher Kyran Moore is done for the season with a knee injury. He becomes the 17th Saskatchewan player on the six-game injured list. Ricardo Louis starts in his slotback spot. In addition, Regina product Mitch Picton goes to the one-game injured list.
