Captain Leacock missed the whole of February with a couple of niggling injuries but the centre-half resumed training on Thursday and will be monitored.
Liddle, who damaged ankle ligaments in December, made his comeback this week in a behind-closed-doors game and Magpies manager Shaun Derry said the midfielder's fitness will be assessed on a day-to-day basis.
Kieron Freeman returned to parent club Derby following last weekend's heavy defeat at Rotherham - and has subsequently signed for Notts County's League One rivals Sheffield United - but Mustapha Dumbuya is fit again after an absence with a thigh injury. Forward Jimmy Spencer is suspended.
