Boundary cornerback Nick Marshall has been placed on the six-game injured list, so Duron Carter was taking reps at defensive back on Tuesday.

Looks like with the injury to Nick Marshall we will see the return of Duron Carter the defensive back. — Arielle Zerr (@arielle_zerr) June 19, 2018

No Nick Marshall. @DC_CHILLIN_8 practising at DB and WR. #Riders — Murray McCormick (@murraylp) June 19, 2018

And the Riders are going to start Carter in Marshall’s absence.

So the plan for @sskroughriders with @DC_CHILLIN_8 is to play cornerback only versus Ottawa … of course things can always change. #riders #CFL — David William Naylor (@TSNDaveNaylor) June 19, 2018

Chris Jones confirms that @DC_CHILLIN_8 will start at CB versus #redblacks for Nick Marshall. Carter will strictly play DB. Marshall is expected to have surgery on an injured finger. #riders. — Murray McCormick (@murraylp) June 19, 2018

Marshall was a training camp and Week 1 revelation with a game-sealing interception for a touchdown off Ricky Ray in the Riders 27-19 victory.

Carter spent an entire practice on defence in training camp. Head coach Chris Jones has said in the past Carter can be the best cover man in the league if he played there full-time.

The 27-year-old started one game at defensive back last season versus Calgary and had an interception return for a touchdown after backing up his trash talk with Stamps quarterback Bo Levi Mitchell.
