Hull FC have announced that Nathan Blacklock is to be released from his contract at the KC Stadium with immediate effect.
The former Australian winger has been hampered by a knee injury this year which prevented him from giving his best for the club, and he will now retire from the game and return home.
Blacklock said: "I'm disappointed I've had to call it a day, but I simply can't give the 100 per cent I want to anymore because of injuries. I can't put my heart and soul into playing.
"Everyone at the club, from the coaching staff to the players and the office staff, have been great to me and I wish the team all the best for the play-offs and the future.
"There are some good young players who deserve a chance. They will have more enthusiasm for the game than I can offer now."
Blacklock arrived at the club from the Dragons last year scoring sixteen tries in twenty four engage Super League appearances, but had to play through the pain barrier to repeat that form this season.
Hull head coach Peter Sharp asummed up: "Tingha (Nathan) has enjoyed a marvellous career. He has achieved some things in rugby league that most people can only dream about.
"He has contributed an awful lot to this club over the last two years and we wish him all the best in the future."
