This year's award was delayed as the Young Lions have been touring New Zealand over the summer. Worrincy follows in the footsteps of some great names such as Andy Gregory and Deryck Fox.
Rob, along with his Young Lions colleague Alex Rowe, is currently on loan at Castleford Tigers, after both players were released by London, as they do not operate an U21 team.
Young Lions Manager Joe Elliott was full of praise for Rob. He said, "Rob thoroughly deserves this prestigious award. His commitment and performances for the Young Lions over the last couple of years have been fantastic."
