Half back Jordan Lilley, hooker Sam Hallas, back row Josh Jordan-Roberts and prop Mikolaj Oledzki are all immediately in contention for places in the Bulls’ squad for the weekend clash with Hull KR.
All four deals are for an initial month.
Leeds CEO Gary Hetherington also confirmed that the deals do not affect the Rhinos’ dual registration arrangement with Featherstone Rovers.
“We have a dual-registration agreement with Featherstone Rovers which works extremely well,” he said.
“That is unaltered, however we are looking to support Bradford Bulls where we can, both through their rugby department and off the field as well.
“To that end, four players will be going on a month’s loan, initially, to bolster the Bradford Bulls first team squad. That is effective immediately.
“The arrangement also suits us as it will provide valuable experience for four of our most promising young players at the start of the season when Brian McDermott has a full squad of players to choose from.”
Bulls co-owner Andrew Chalmers is also very pleased that the Rhinos have helped out their old rivals in this way.
“I’d like to thank Gary Hetherington for the help he has given us and we will look to continue to develop this relationship for the benefit of all the stakeholders.”
