Add one more injury to the Saskatchewan Roughriders’ infirmary list following Thursday’s closed practice ahead of Saturday’s visit to Calgary.

Canadian defensive back Elie Bouka is out this week, according to Green and White head coach Craig Dickenson, after tweaking his hamstring Wednesday in practice. Dickenson added that veteran import defensive end A-C Leonard is questionable after also being hurt in practice. But, on the positive side, Dickenson says receivers Shaq Evans and Duke Williams are on the right track to play in the second place showdown in the C-F-L West.
