Thomas blow rocks Wales on Four Nations eve

The news was broken by Emanuele Palladino, from Thomas’s management company Distinct, just four days before the former British and Irish Lion was due to play for Wales against England in the Gillette Four Nations Series.

Palladino said in a statement: “We can confirm that Gareth Thomas is officially retiring from both international and club rugby with immediate effect.

“This marks the end of what has been a remarkable career for a remarkable person.

“Gareth hopes that through his achievements both on and off the field he has left a lasting legacy within the game.”

The 37-year-old Thomas switched codes with Wrexham-based Super League club Crusaders two years ago and, following their demise, was poised for a shock move to Wigan.

Thomas, whose last game of rugby was for Crusaders on July 9, said he took the decision after coming to the conclusion that he could no longer give 100 per cent.

“I have listened to and discussed this decision with many of my family and close friends,” he said. “My mind has told me that the time to retire is now.

“If you can’t give 100 per cent 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.”

Born in Sarn, Bridgend, Thomas spent most of his rugby union career with Cardiff, although he won the Heineken Cup in 2005 during a stint with Toulouse.

After making his Test debut against Japan in 1995, Thomas became the first man to win 100 caps for Wales, a record tally that was recently surpassed by Stephen Jones.

He made three appearances on the 2005 British and Irish Lions tour to New Zealand and was appointed captain for the second and third Tests following an injury to Brian O’Driscoll.

Thomas hit the headlines in December 2009 by announcing he was gay and three months later switched codes to play rugby league.
