Cody Fajardo may not play Saturday when the Saskatchewan Roughriders host Edmonton.

Head coach Craig Dickenson says the Green and White’s starting quarterback pulled a back muscle during practice Wednesday and is questionable. If Fajardo declares himself unavailable, Isaac Harker will get the start at quarterback with Brian Bennett also likely to get some reps.

At 12-5, the Riders have a chance to nail down first place in the C-F-L West for the first time in 10 years with a victory. Game time Saturday is 2 p.m. at Mosaic Stadium and on T-S-N.
