Dual-code Wales international Gareth Thomas has announced his retirement from all forms of rugby with immediate effect.
The 37-year-old spent 13 years playing rugby union before switching codes to join Crusaders in 2010.
"I have listened and discussed this decision with many of my family and close friends. My mind has told me that the time to retire is now," Thomas said in a statement.
"If you can't give 100% to rugby then you can't do it justice. This is a sad day, but I know that my time has come to an end as a player. My passion for the amazing game will never end or leave me however.
"I do not know what lies ahead, but I feel the challenge of something different excites me more than another year of rugby."
In December 2009 Thomas became the first openly gay rugby union player.
