Wakefield Trinity Wildcats have signed Cronulla Sharks prop David Fifita on a deal until the end of the season.
The 26-year-old Tonga international is unlikely to make his Wildcats debut at Huddersfield on Sunday.
The Super League side have the option of a further year on his contract.
Coach Chris Chester said: "It is a massive signing for the club. We have monitored him closely over the last six to eight weeks and know he will bring some real punch and aggression."
