Hull KR have beaten Castleford Tigers to the signing of Newcastle Knights back row forward Constantine Mika on a two-year contract.
The Samoa international, 22, looked set to join Cas but has now decided to link up with new KR coach Craig Sandercock, who was Knights assistant.
Sandercock told BBC Radio Humberside Mika will be an adequate replacement for the departing Clint Newton.
"He's exactly what we need, a genuine back rower," he said.
"I'm really excited about securing him for Rovers."
The Robins coach does not think Mika will struggle to live up to the expectation of being compared to the former NRL Grand Final winner.
"I think they fans will appreciate what he has to bring to the table. He's a slightly different player to Clint but he's someone that I think will be a quality acquisition for us," added Sandercock.
New Zealand-born Mika is Rovers' sixth pre-season signing, following Ryan O'Hara, Mickey Paea, Graeme Horne, Keal Carlile and Lincoln Withers' move to Craven Park, subject to him receiving a work permit.
