Leigh have confirmed the signing of Greg Richards from St Helens on a contract to the end of November 2018.
The 22-year-old progressed through the ranks of community club Barrow Island, before joining St Helens Academy.
He played for England U18 at the age of 16 and made his Saints first team debut at Castleford in 2013, five days before his 18th birthday.
While still a teenager Richards played in Saints’ Grand Final victory over Wigan at Old Trafford in 2014.
Leigh boss Neil Jukes said: “Greg has been at an elite club for a number of years and played a lot of games. He is going to bring good habits and plenty of experience, even though he has youth on his side.
“Greg has really bought into our vision and what we want to achieve at Leigh Centurions.
“He sees the opportunities that are in front of us, but first of all wants to be part of achieving our goals of maintaining our Super League status.
“Greg will add competition and energy to the middles and he has shown he can do it at the highest level.”
