Castleford Tigers have signed Warrington Wolves centre or wing Ryan Shaw on a one-month loan deal.
The 19-year-old has represented England Under-18s and played for the Wolves at Under-20 level.
Tigers head coach Ian Millward said: "He is a powerful young centre. He gets to train with us and we get to see if he is ready for Super League.
"He's a talented player who Warrington have high hopes for. We'll play him in pre-season and see from there."
