Castleford have signed 19-year-old outside back Tuoyo Egodo from London Broncos on a two-year contract.
Egodo has spent the last three years with the Broncos academy and was loaned out to League 1 club Hemel Stags in 2016.
Castleford coach Daryl Powell said: "Tuoyo has come through the London system and looks a really exciting player for the future.
"He plays the game really physical and I'm really looking forward to see how he develops within our system.
"He is quick and strong with an ability to run straight over the top of people. He's just come out of U19s rugby league but he is certainly one to keep an eye on and I'm delighted he has agreed to sign at the Tigers."
