Castleford have handed two-year contracts to teenage trialists Rob Worrincy and Alex Rowe. Worrincy, a wing/full back and prop Rowe joined from London Broncos Academy side last season and have been regulars in the Tigers Senior Academy side.
Worrincy made his senior debut in the 44-18 defeat to Bradford last weekend.
"They have some way to go and plenty to learn, but they have real potential to become first team players," said Junior Development manager Dean Sampson.
