O'Connell hangs up his boots
The 36-year-old suffered a serious hamstring injury during last year's World Cup. He planned to see out his career with French giants Toulon, but has now decided to hang up his boots after struggling to recover from the setback
"It is with deep regret that I have decided to retire from professional rugby following medical advice," O'Connell said in a statement.
"I would like to take this opportunity to thank all at Rugby Club Toulonnais for their understanding and support over the past few months.
"Since sustaining the injury at the World Cup I have been fully focused on returning to fitness and starting an exciting new chapter for both myself and my family in Toulon. Unfortunately this will no longer be possible.
"I have been blessed to be a professional rugby player for over 14 years and to be part of Munster and Ireland teams that have experienced success.
"I have played with some of the best players to ever line out in the red of Munster and the green of Ireland and have had the privilege of captaining my country.
"I would like to thank those at Young Munster RFC, Munster Rugby, the IRFU and Lions Rugby who have supported me over the course of my playing career.
"Special thanks must go to my wife Emily for her unwavering support through the good and the bad and to my parents Michael and Shelagh.
Lastly I would like to thank everyone who has supported the teams I have been a part of. The support you have shown me is humbling and an immense source of pride for both myself and my family."
