The Bulls have signed wing or stand-off Jordan Aitchison, 18, from Keighley Cougars on a two-year deal and prop Jonny Payne, 19, from Castleford on a one-year deal.

Their acquisition – along with Whitehaven’s Jay Rossi – follows the signing of highly-rated Leeds Rhinos academy stand-off Marcus Elliott in September.

Bulls player performance manager Stu Barrow said: “We’re delighted with the signings we’ve made.

“I know Jay through our time together with the England academy and Jordan is a player we’ve followed closely for the past 12 months.

“He’s an elusive runner and has been playing on the wing for Keighley but we see him more as a stand-off.

“We have brought in four young lads who are hungry to succeed.”
