Castleford academy prop Dan Fleming has earned a two-year full-time contract after catching the eye in the Under-20s.
The 19-year-old, 6ft 3in, 105kg, forward joined the Tigers from Halifax before the start of last season.Castleford coach Ian Millward said: "We'll bring Dan into our top squad next season. He's one of those late developers, who has gradually matured into a big presence."
Fleming said: "I can't wait to get training full time with the team. I've worked really hard to get this opportunity and I'll be doing all I can to make the most of it."
