Bradford Bulls are likely to be unchanged as they aim for a third consecutive home win. Second rower James Donaldson is on stand-by to make his first appearance of the season if either Chev Walker or Jamie Langley fail late fitness tests, while coach Francis Cummins has called hooker Adam O'Brien into his 19-man squad.

St Helens coach Nathan Brown is expected to switch Tom Makinson to full-back in place of the injured Paul Wellens, with either Ade Gardner or Gary Wheeler taking over on the wing. Jon Wilkin captains the side in Wellens' absence.
