Plymouth Devils captain Ben Barker could return to the side on Friday, just a week after having an operation on a broken leg.
Barker was after the injury against Sheffield, but could return against Newcastle.
"Ben is optimistic that he will be able to race against Newcastle," said promoter Mike Bowden.
"But I need to sure that he is fully fit before including him in the side," he added.
"I have Emiliano Sanchez on standby to come in as a guest replacement if necessary."
