Championship club Bradford Bulls are set to terminate the contract of former Wakefield Trinity Wildcats scrum-half Harry Siejka.
The 23-year-old Australian joined the Bulls on a two-year contract last October after a spell at Belle Vue and made 15 appearances in 2015.
“We wish him well and all of the best for the future,” said Bradford managing director Steve Ferres.
“The club is currently in the process of terminating his contract by mutual consent.”
Bulls have signed 28-year-old winger Johnny Campbell from Batley Bulldogs on a two-year contract. Campbell spent six seasons at Batley and is recovering from a badly broken leg.
Hunslet Hawks have re-signed utility-forward Chris Buttery on a one-year deal, after he had a spell out of the game due to a knee injury.
Buttery, 29, has also played for Leeds Rhinos academy, Doncaster and Batley and Hawks director of rugby Darren Williams said: “Chris has returned to fitness and decided he has got the bug back again and wanted another go at the semi-professional game.
Featherstone Rovers have announced that Billy Mallinson has joined the club as head of strength and conditioning. He has worked for both Hull clubs and is a former teammate of Jon Sharp.
He said: “I know Jon well and he’s brought together some great young athletes who will be a pleasure to work with.”
