Former Super League prop Mitch Clark has joined Championship club Sheffield Eagles on a two-year deal from 2024.
Clark has spent the last two seasons in the Championship with Thunder, playing 50 games for the North East outfit.
Clark, who represented the New Zealand Maori team in 2017, is the son of former Bradford, Leeds and Featherstone player Trevor Clark.
The Pontefract-born forward has made almost 200 career appearances for Doncaster, Bradford, Hull KR, Castleford, Leigh, Wigan, Pia and Newcastle.
Sheffield Eagles boss Mark Aston delighted to welcome Mitch Clark to the Steel City
Aston said: “We’re happy to be bringing Mitch on board.
“He can really bring something to the team, some power into the pack that is much needed across the course of a season.
“He’s good friends with the likes of Jesse (Sene-Lefao) and QLT (Quentin Laulu-Togaga’e) so he’ll fit into the group seamlessly.”
Elsewhere in the Championship: Reece Lyne makes Doncaster move
Elsewhere in the Championship, Doncaster have signed former England international Reece Lyne on a three-year contract from relegated Super League side Wakefield Trinity.
The 30-year-old centre has spent the last 11 seasons with Wakefield, scoring 64 tries in 233 appearances for Trinity.
Lyne, who was part of the England squad for the World Cup 9s in 2019, came through the ranks at hometown club Hull FC.
The Hull-born centre has now left Belle Vue to join Doncaster ahead of next season on a deal until at least the end of 2026.
