Bulls coach Mick Potter has been able to call on only 18 fit senior players for the second successive Super League match ahead of Sunday's visit of leaders Huddersfield.
Potter has seen his squad decimated by injury and suspension this season, and up to a dozen players will play no part this weekend.
Scrum-half Luke Gale is not ready to return from a two-month absence due to damaged ankle ligaments, but the Bulls are boosted by the return of Chev Walker and Karl Pryce after injury.
Youngsters Callum Windley, Jay Rossi and Matt Bailey were in the 19-man squad for last week's match against Doncaster but have not been called on this week as Potter has named his only 18 senior players available.
Bulls squad: Addy, Ainscough, Bateman, Burgess, Diskin, Elima, Hargreaves, Jeffries, Kopczak, Langley, Lulia, Manuokafoa, Olbison, Platt, Pryce, Purtell, Walker, Whitehead.
