Martin is struggling with the hip injury he sustained in the 5-0 defeat to Swindon at the weekend, so veteran shot-stopper Steve Phillips looks set to make his first appearance of the 2013/14 campaign.

Meanwhile, Ollie Turton (foot), Thierry Audel (ankle) and Mathias Pogba (knee) remain sidelined.
