CHEV Walker, Jean-Philippe Baile and Danny Williams have all been cleared to play against Hull KR this weekend, with Harry Siejka, Vila Halafihi and Adrian Purtell missing out.

Half-back Siejka has been sidelined for up to 10 weeks after undergoing ankle surgery on Wednesday and centre Purtell is yet to have recovered from an injury sustained during last Sunday's beating of London Broncos.

Jake Mullaney is also set to miss out for the fourth game running due to the hamstring injury he picked up against Workington on March 29.

Bulls’ 19-man squad: Adam Henry, Adam O'Brien, Adam Sidlow, Alex Mellor, Chev Walker, Chris Ulugia, Dale Ferguson, Dan Fleming, Danny Addy, Danny Williams, Epalahame Lauaki, Etu Uaisele, Jay Pitts, Jean-Philipe Baile, Lee Gaskell, Lucas Walshaw, Paul Clough, Ryan Shaw, Tom Olbison.
