Castleford have signed half-back Danny Richardson from St Helens on a three-year deal for an undisclosed fee.
The 23-year-old is Castleford’s replacement for Luke Gale, who has joined Leeds on a three-year deal from 2020.
Richardson made 59 appearances for St Helens, scoring eight tries and kicking 175 goals.
Tigers 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.”
Richardson added: “There were a few clubs enquiring about me for next year but the minute my agent came to me and told me about Cas being interested, I jumped at the chance and couldn’t wait to get the deal over the line.
“With the coaching staff we have and the way other half-backs have developed whilst they’ve been at the club over the years, I thought that if there was a place for me to improve and get the best out of myself it was going to be with the Tigers.”
