Hunslet have signed experienced prop Alex Rowe from Newcastle on a one-year contract.
The 34-year-old, who has played for Malta internationally, made 13 appearances for Thunder in League 1 last term. He has previously played for London, Castleford, Doncaster, Sheffield and Batley.
Hunslet coach Gary Thornton said: “It’s a massive boost for us to have a player of Alex’s experience and ability join us at this stage of the season.
“He’s a big robust prop forward and a handful for any defence. I’ve been in contact with him for a while, and we almost got him on loan last year until Newcastle pulled the plug on the deal, so I’m really pleased he has now signed following his release from the Thunder.
“He has loads of experience, mostly at Championship level, so he will complement our pack really well.
“He is well known and well respected in the Championship and League 1 and hopefully he can reproduce his destructive running and big defence for us in the coming campaign, and add to what is already a pretty formidable pack.”
