Huddersfield Giants half-back Luke Robinson has been forced to retire at the age of 31 due to a hip injury.
The former England international made the decision after consulting with specialists.
Robinson - who has also represented Wigan Warriors, Castleford Tigers and Salford - will now focus on his rehabilitation but hopes to stay with the Giants in some capacity.
"In many ways the decision was taken out of my hands by listening in the cold light of day to what the specialist said. Put simply my long term mobility was greatly at risk if I continued to train and play the sport," he told the Giants' official website.
"You never want to hear those sorts of words and it does shock you but after a few days the message sinks in and you have to do what's right for yourself and your family.
"My immediate future will be rehabilitation from an operation which the club are fully supporting me through and then we have said we'll sit down and look at where I can be of benefit to the club.
"Over these past few years I have come to regard this as my club and it's the only one I want at be at and it is how I've felt for a good while now.
"Words cannot describe how difficult it was telling the lads of the decision to hang the boots up - especially at the current moment when we are low on numbers - but as I keep saying I really have no choice."
