EMMERSON Whittel and Mason Tonks could make first-team debuts for the Bulls this weekend after Jimmy Lowes made a raft of changes for the final-round trip to London Broncos.

Academy product Whittel and on-loan Leeds youngster Tonks have featured regularly for the Under-19s this season and could now follow Brad Adams' footsteps in making the step up to Super League.

Adams is again included after making his bow in last weekend's home defeat to Widnes but Lowes has swung the axe and made six changes.

Out of last week's 19-man squad go Matty Blythe, Jamal Fakir, Danny Williams, Oliver Roverts and Dale Ferguson while Lee Gaskell misses out with a knee injury.

There will also be no swansong for Matt Diskin, who will retire at the end of an injury-disrupted campaign.

Bulls' 19-man squad: Brad Adams, Danny Addy, Joe Arundel, Jordan Baldwinson, Nathan Conroy, James Donaldson, Jamie Foster, Luke Gale, Adam Henry, Brett Kearney, Manase Manoukafoa, Alex Mellor, Adam O’Brien, Tom Olbison, Jay Pitts, Adam Sidlow, Mason Tonks, Chev Walker, Emmerson Whittel.
