Garreth Carvell has announced his retirement in order to focus on his role as player-welfare manager at Salford Red Devils.
The former Great Britain international prop, 34, moved to Salford in April from Featherstone to take up the role.
"Although the mind is still willing unfortunately the body has declared it's time to stop," he told reporters. "I'm awaiting a knee replacement and surgery on my neck to replace three prolapsed discs so a lot of recovery time is needed.
"I've got to the stage where I can't kick a ball around the garden with my son and when the little joys in life like that are out of your reach it's time to take a step back and realise that the moments are not available forever."
He started his career at Leeds and has also played for Gateshead, Hull FC, Warrington and Castleford.
