Wrexham have a doubt over striker Jake Speight, who was forced off during Saturday's 2-1 win at Tamworth.
Danny Wright should be fit after coming through the game unscathed following three weeks out with a back problem.
Brighton could face the trip north without two of their main strikers, Craig Mackail-Smith and Will Hoskins.
Mackail-Smith was forced off on Saturday with a severe eye injury while his replacement, Hoskins, felt twinges in his knee on his comeback.
