Centre-half Leacock missed the win at Watford with a tight hamstring while leading scorer Hulse has been absent for the last two matches with the same problem.
However, on-loan defender Fredrik Stoor is out after having an injection in his troublesome ankle injury so Paul Connolly will revert to his usual position at right-back having provided cover in the centre of defence recently.
Shaun Barker’s thigh problem will keep him sidelined and fellow centre-back Miles Addison remains out with a foot problem but is not too far away from a return.
Forward Kris Commons will resume training shortly following two months out with a hamstring injury. The Scotland international could take part in a reserve-team fixture next week.
