Luke Fitzgerald has been forced to retire from rugby on medical grounds.
The Leinster and Ireland star picked up a neck injury in the Guinness PRO12 Final against Connacht in May.
The 28 year old utility back has been advised to retire on medical grounds as a result.
Fitzgerald has long struggled with numerous injuries, which have curtailed a hugely promising career.
The ex-Blackrock College student made his Leinster debut in September 2006 and went on to play 154 times for the Blues.
He also made his Ireland debut in 2006 against the Pacific Islands, going on to win 34 caps in Green- the last of which came against Argentina at the World Cup last year, when he scored a try.
Fitzgerald also played for the British & Irish Lions in their tour of South Africa in 2009.
He won a Six Nations title with Ireland in 2015 and a Grand Slam in 2009 and picked up three Heineken Cups, a Challenge Cup and three PRO12 titles with Leinster.

"I've had a wonderful rugby career which makes it easy for me to move on to the next stage of my life", said Fitzgerald, speaking to leinsterrugby.ie.
"It's been an amazing journey in which I got to experience the highs and lows that come with professional sport and I have learned a huge amount from each experience.
"I'm now building on that foundation through completing my business degree.
"I'm very thankful for the opportunities I have had, the people with whom I've worked and the lifelong friends I have made.
"I would also like to take this opportunity to thank all the medical staff and coaches I've worked with throughout my career and at Blackrock College.
"It's been an honour and a privilege to represent my province, my country and the British & Irish Lions during my career and I'm glad to finish my career as a 'one club man'.
"The support I got whilst playing for all three teams during the good times and the tough times is something I'll cherish and never forget for the rest of my life.
