Warrington have signed Salford second-rower Ben Murdoch-Masila for a fee of £175,000 as they continue to shape their squad for next season.
The 26-year-old joins the Wolves on a three-year deal as one of the best back-rowers in Super League following an outstanding 2017.
New head coach Steve Price said: "Ben is a hell of a ball runner. He's had a stand-out season this year at Salford earning him a place in the Dream Team.
"I have watched Ben grow with interest when playing back in the NRL to how he has transformed to today.
"I see a lot of upside in Ben as to what he can bring to the club and team, and we will look to guide him into becoming an even better player."
The hulking forward joined Salford ahead of the 2016 season after spells with NRL clubs Wests Tigers and Penrith Panthers and had a huge impact, scoring 22 tries in 60 appearances.
"It's an honour to become a part of a club with such great history," said Murdoch-Masila, who is representing Tonga at the World Cup.
"I am really excited for what we as a club can achieve in the future and am really looking forward to hooking up with Steve and the boys and getting stuck in for 2018."
Murdoch-Masila is Warrington's fourth major signing for 2018 - following the additions of Sitaleki Akauola, Bryson Goodwin and Tyrone Roberts - as they aim for a significant improvement on this year's ninth-placed finish.
"Ben will be a big asset to the squad - bringing power, size and punch," said chief executive Karl Fitzpatrick.
"He's been outstanding since joining Salford, which resulted in a justified selection for the Super League Dream Team at the end of the 2017 campaign.
"The transfer demonstrates our commitment and intent for the 2018 season and beyond.
"Ben is the fourth new quality player that has put pen to paper and as with all quality signings we've had to work hard to fend off competitors to land each and every one."
