Long-serving St George Illawarra Dragons winger Jason Nightingale will retire at the end of the NRL season.

Nightingale has scored 110 tries in 265 appearances for the Dragons and played 33 times for New Zealand in his illustrious career.

The flyer, who scored two tries in the 2010 Grand Final victory over the Sydney Roosters, has decided to bow out at the age of 31.

He said: "There have been so many great seasons personally. To be recognised for so many different reasons that are celebrated at the Dragons, they all still sit on my mantelpiece very nicely.

"The 2010 grand final win was the highlight for me and my family. There are so many fond memories from that day and the season as a whole. Although now is great time to reflect, there are still plenty of memories to be made this season yet. 

"However I'm also look forward to more family time with my second child on the way. My wife Bianka has sacrificed a lot for my career. She's been selfless by supporting me throughout my career, while also building one of her own."

Dragons chief executive Peter Doust said: "Jason has always represented himself, his family and the Dragons with distinction and has always been committed to supporting the club's visions both off and on the field.

"He is an outstanding role model who typifies the club's values and we have been privileged that he has remained loyal to the Dragons for so long. He signed eight contracts to remain at the Dragons.

"We are a development club who have always invested and provided opportunities for players in the local area and he epitomises everything we stand for. We couldn't be prouder of what Jason has achieved throughout his career."
