Sean Long, the only player to win the Lance Todd Trophy three times, has announced his retirement at the age of 34 to take up a coaching opportunity.
Long has made only 21 appearances in two injury-ravaged seasons with Hull, but enjoyed 12 successful years with St Helens, including being man of the match in three Challenge Cup finals.
After a series of fitness problems at Hull, he has been out since June with a shoulder injury and was not offered a contract for next season. Hull have already recruited new half-backs in Aaron Heremaia from the New Zealand Warriors and Jamie Ellis from Leigh.
"This isn't the time I planned to bow out, or the way I wanted to do it either," Long told the Hull Daily Mail. "Making this decision has been killing me.
"It has been such a difficult decision, but a coaching opportunity has come up, which I have to take up now."
Long began his career with his hometown club, Wigan, moving briefly to Widnes but finding his niche as Saints' scrum-half and winning a total of 23 caps for Great Britain and England.
It has been a career studded with controversy, with a suspension for illegal betting and an early exit from an Australian tour. On Twitter, however, he predicted that he will "look back on what I've achieved with a smile".
He did not reveal where he will begin what he hopes will be an equally eventful coaching career, but he will inevitably be linked with a possible return to Saints as part of Royce Simmons' staff.
The England winger Peter Fox is to rejoin Wakefield on a three-year deal from Hull KR.
