Hunslet have confirmed prop forward Matt Nicholson, half-back Shaun Roberts and trialist Niall Walker have all signed contracts with the club until the end of the season.
Nicholson is a former Leeds Rhinos junior and has also had spells at York City Knights, Featherstone and Doncaster.
Roberts was recently on trial at York and previously played at Sheffield for three years, while Walker scored a try as a trialist on his debut in the defeat at Oxford before sustaining a knee injury and is currently undergoing rehabilitation.
Head Coach Gary Thornton said: “I’m delighted to have Matty on board. I’ve worked with him previously at both York and Doncaster, and he is a quality player and a quality individual.
“He has had a horrendous time with injuries which has hampered the progress of his career, but he is good to go now having fully recovered from his latest injury, and is looking forward to pulling on the Hunslet jersey.
“To have him on board for the rest of the season will be a massive boost to us. He is very professional and will bring a fantastic attitude and experience to the group.
“Shaun is a talented half-back- a tough defender with a great kicking game and organisational skills.
“He has big ambitions, a fantastic attitude, and is determined to play at the highest level he can, and I’m glad to be able to give him that opportunity with Hunslet.
“I’m really looking forward to working with him and seeing the value he can add to our squad.”
