Tom Flegler will join teammate Herbie Farnworth at Redcliffe next NRL season after the Brisbane prop's four-year deal at the Dolphins was confirmed.
The State of Origin forward's signing on Sunday comes just two days after in-demand centre Farnworth's signature was trumpeted by the Dolphins.
The 23-year-old Flegler has played 74 NRL games since his 2019 debut, despite constant suspensions stemming from his aggressive style of play.
He'll link with emerging prop Tom Gilbert and the experienced front-row core of Jesse and Kenny Bromwich, Felise Kaufusi, Jarrod Wallace and Mark Nicholls next year.
"The Dolphins have always said that our recruitment strategy was about building a club with a strong future, rather than just for season 2023," Dolphins boss Terry Reader said.
"The signature of Tom and Herbie Farnworth are great examples of that strategy at work.
"We are very excited about what these two players can add to the squad we have already assembled."
