The striker, who was red carded at Glanford Park back in November after apparently elbowing Nathan Stanton, is suffering with a back strain.
"He's not definitely out, but we will wait and see," explained Darlo assistant-manager Mick Tait."
"Apart from him everyone who played last week at Rochdale is fit."
Iron manager Brian Laws has said that United have no fresh injury doubts, but is expecting a tough game.
"I've got no injuries to contend with, but we know it won't be easy," he said today.
