A puzzling losing skid continues for the Saskatchewan Roughriders.

They dropped their third in a row last night, losing to Edmonton 39-24 on the road. The Rider defence struggled again against the run, giving up 160 yards on the ground.

The loss means that first in the west is now officially out of reach for the Riders, and they will host the West Semi-final against either Edmonton or BC.

The Riders visit the Lions next Sunday.
