Cooper replaced the suspended Yassin Moutaouakil at right-back against Fleetwood last weekend but suffered a groin injury in the 1-0 defeat.
Moutaouakil is still banned so Danny East could step in if Cooper is ruled out, while centre-half Devera will be checked over after missing Saturday's game with a hamstring injury.
Striker John Marquis could make his debut following his recent loan switch from Millwall.
