Bulls coach Francis Cummins has recalled young hooker Adam O'Brien for Sunday’s Tetley's Challenge Cup quarter-final at home to Warrington.

O'Brien replaces Huddersfield prop Antonio Kaufusi, whose four-match loan spell expired after last week’s victory over Wakefield.

The Bulls are trying to extend the loan but Kaufusi would have been cup-tied this week anyway, along with on-loan Hull FC centre Joe Arundel, who represented the Black and Whites against Salford in the competition earlier in the season.

Bulls' 19-man squad: Danny Addy, Matty Blythe, Matt Diskin, James Donaldson, Jamal Fakir, Dale Ferguson, Jamie Foster, Luke Gale, Lee Gaskell, Luke George, Adam Henry, Elliot Kear, Manase Manuokafoa, Adam O'Brien, Tom Olbison, Jay Pitts, Adrian Purtell, Adam Sidlow, Chev Walker.
