Castleford this week swooped to the signing of Samoan Test International three-quarter Willie Isa from Melbourne.
Tigers head coach Terry Matterson said: “I’m excited to have enticed Willie to the Tigers.
“With the sudden retirement of James Evans it was important that we strengthened in the centre positions and we feel with Willie’s acquisition we have more than covered that area.
“He is a very strong and allusive centre who will bring some genuine speed to our backline.”
He said: “My coach at Melbourne Storm, Craig Bellamy speaks highly of Terry and I’ve heard a lot of good things so I’m pretty excited about working with him at Castleford.
“I can guarantee that I will do my best for the players and fans at the club. The fans play a lot of money to come to games and I will be out there doing my best for them every game.”
Isa is the club’s seventh new signing this closed season. He joins Richard Mathers (Warrington), Danny Orr (Harlequins), Nick Youngquest (Crusaders), Nick Fozzard, Jacob Emmitt (St Helens) and Martin Aspinwall (Huddersfield) in signing for the Tigers.
