Castleford have confirmed the signing of St Helens half-back Danny Richardson on a three-year deal.
The two clubs have agreed an undisclosed fee for the player, which is understood to be in the region of £60,000.
Richardson is seen by the Tigers as a replacement for Luke Gale, who has joined Leeds, and a half-back partner for Jake Trueman.
Castleford director of rugby Jon Wells said: “We are delighted to announce the signing of Danny on a three-year contract.
“His signature means that we now have two young, English, international halves to spearhead this team.
“Danny is an exciting player – fast, creative and a high-quality goal kicker – and we feel he is the right man to unlock the huge potential in our backline.
“He comes from a great system at St Helens and I would like to place on record my thanks to Eamonn McManus and Mike Rush from the St Helens club for their professionalism during the negotiations, which will now see Danny progress his career and contribute as a Tiger from 2020 onwards.
“We have a fine record of improving players, vast international experience in the coaching group, and at 23, Danny will have his best years ahead of him here at the Mend-A-Hose Jungle.
“Danny will be relocating to Yorkshire and he joins us for day one of pre-season in just under a month from now – and he can’t wait to get started.”
Head coach Daryl Powell said: “We have just made a signing that should excite and engage all of our supporters as we look towards 2020.
“To work alongside Jake Trueman, we have signed one of the best young half backs in rugby league.
“Danny is a player of real quality with the potential to play international rugby.
“He has a sharp rugby mind alongside his ability to kick the ball in a special way both for goal and tactically.
“We are looking forward to helping Danny go to the next level in his career and can’t wait to get started towards next season.”
