Right-back Herd missed the midweek Carling Cup defeat at Bristol Rovers after picking up a knee injury.

Should he not make it, then Lewis Chalmers will continue to fill in at the back.

Waddock must also decide who to play in goal in the League Two clash at Spotland.

Mikhael Jaimez-Ruiz started the 3-1 win over Darlington last weekend but Waddock opted to give Clark Masters a debut against Rovers and he impressed by saving a penalty.

Left-back Dean Howell is recovering from a hip operation and is expected to be out of action for several more weeks while Anthony Charles remains sidelined with a slight knee problem.
