Teenager James Donaldson and Matt Cook have been brought in to the Bulls’ 19-man squad for Friday night’s trip to Headingley Carnegie.

They replace Glenn Morrison (ribs) and Julien Rinaldi (foot) for the clash against champions Leeds Rhinos.

With hooker Rinaldi missing, Odsal boss Steve McNamara could have been tempted to throw Wayne Godwin straight back into the mix on his return from injury.

But, after nearly four months out with a broken leg, Godwin will instead ease back into action in the Reserve Team curtain-raiser between the sides.

Loose forward Donaldson, 17, may make his Super League debut although Paul Sykes (hamstring) is likely to be fit to take one of the vacancies.

Cook is also in the reckoning having scored two tries in two games since being dropped to the Reserve Grade.

BULLS: Sykes, Langley, Sheriffe, Burgess, Donaldson, Scruton, Menzies, Newton, Whitehead, Cook, Halley, Nero, Lynch, Kopczak, Jeffries, Tadulala, Worrincy, Platt, Deacon.
