Doncaster Knights have snapped up Jerry Cronin, James Tincknell and Ben Sowery as they continue to put together a strong squad for next season.
Tighthead prop Cronin will join from Heineken Cup finalists Ulster, with the 28-year-old having impressed with his work-rate in the loose and his scrimmaging ability.
Knights director of rugby Brett Davey told the club's official site: "Jerry fits the exact kind of player we wanted to bring in. His experience with Ulster is a big plus to us and he is sure to fight hard for his place in the side."
Tincknell, who can play on the wing or in the centres, was released by Leeds at the end of the season - with the 23-year-old having spent the majority of last season on loan at Wharfedale.
He looked set for a bright future at Leeds before his career stalled after he suffered a serious car accident. However he is looking forward to kick-starting his career at Castle Park.
Tincknell said: "I'm really excited to join Doncaster, they are a very ambitious club with a brilliant set-up and first class facilities.
"I'm looking to stake a claim for a starting spot and continue with my rehab by playing regular rugby for the Knights."
Former England Under-18s hooker Sowery also joins having played for Leeds and Wharfedale.
Having started his career at Harrogate, Sowery spent time at the Carnegie academy before heading to Wharfedale.
And the 21-year-old is ready to fight for his place in the Doncaster pack.
"This is a massive opportunity to me and I am very grateful for my chance, but now I have to stake a claim for my place in order to progress my game," he said.
