York Knights complete double signing ahead of maiden Super League campaign

Roberts, a 20-year-old half-back who has gained experience during loan spells with Swinton Lions, Rochdale Hornets and Widnes Vikings, links up with the Knights following his release by St Helens.

Utility back Williams, meanwhile, returns for a second spell after scoring 10 tries in 26 games in 2024.

Applegarth has welcomed the injection of fresh blood as York continue to build towards their maiden Super League campaign.

"Will comes very highly rated from St Helens," said the Knights boss, whose side host defending champions Hull KR in round one on February 12.

"They're blessed with an abundance of talent in the halves and I've watched Will for a couple of years now. I really like what he's about. I think he's going to be a quality half-back over the next two to three years.

"Nikau is a player I've been chasing ever since he had to go back to Australia. We didn't want him to leave in the first place and we're delighted we've got him back.

"He picked up exactly where he left off and has just slotted straight back in. I think he's going to be a massive part of the squad this year and I'm delighted we've got him back on board."

Williams, who has also played for Whitehaven and Newcastle Thunder, did not hesitate when York came calling.

"Clint (Goodchild, owner) got in touch and gave me the opportunity to come back," said the 26-year-old. "I was buzzing and took it with both hands.

"I'm really enjoying being back. It's like I never left, to be honest."
