The Cardiff Blues forward was charged with drink driving after driving a golf buggy down the M4 motorway following Wales' spectacular 31-24 victory over Scotland at the Millennium Stadium.

The 28-year-old was immediately removed from Gatland’s squad and Powell fears he may never play for his country again.

“After beating Scotland the way we did I had a few too many beers and enjoyed the night a bit too much," Powell said.

“I should have been thinking more about what I was doing and, if I had, I would never have done it. It was a stupid prank which went badly wrong. I regret terribly what I did.

“I know it could cost me my international career and that tears me up inside every time I think about it.

“Gutted is not a strong enough word for how I feel. I've brought it all upon myself and I realise now that it could have a serious effect on my future.

“I have let Wales down, my family, the fans and everyone involved with rugby, especially Warren Gatland, who gave me the chance to play for my country.

“There is a danger that I won't get the chance to play for Wales again. It's going to be tough but it's up to me to rebuild my career and get it back on track.”
