The 37-year-old lock played 158 times for Wales and made 12 British and Irish Lions Test appearances.

Wales flanker Justin Tipuric, who won 93 caps, had earlier announced his decision to step down from Test rugby.

The players’ decisions come less than four months before Wales’s Rugby World Cup opener against Fiji in Bordeaux, and both had recently been named in a 54-player preliminary training squad for the tournament by head coach Warren Gatland.

Writing on his Instagram page, Jones said: “Having been selected in this year’s preliminary Rugby World Cup squad, and after ongoing dialogue with the coaching staff and WRU (Welsh Rugby Union), I have decided to step away from the international game.

“So, after 17 years, I look back on special memories with Welsh greats and future Welsh greats.”

Gatland was quick to pay tribute to one of his finest servants.

“I would like to congratulate Al on a phenomenal international career," Gatland said.

“His leadership, dedication and determination are second to none, and he has been an incredibly special player for Wales over the past 17 years.

“Every single time he has taken to the training pitch or put on the red jersey in a Test match he has given his absolute all, setting standards and leading by example.

“I am very fortunate to have been able to have worked with him with Wales and with the Lions.

“Al’s passion and commitment for his country are limitless, and he has been an important pillar for the game in Wales.

“He and his family can be immensely proud of all he has achieved and in knowing he leaves a lasting legacy in Welsh rugby.”

Tipuric’s decision comes just a month after his fellow Wales back-row forward Josh Navidi called time on his career, being forced into retirement because of a serious neck problem.

Tipuric, 33, was an integral figure in Wales teams for more than a decade, helping his country win four Six Nations titles, including two Grand Slams.

He was awarded his Wales debut by Gatland against Argentina 12 years ago and played in the 2015 and 2019 Rugby World Cups.

Tipuric also made one Test match appearance for the Lions on their 2013 tour to Australia.

Gatland added: “Justin has been an integral player in the Wales back-row since he made his debut back in 2011.

“He is quite quiet off the pitch, but his skill-set and his work-rate really set him apart from others.

“He doesn’t like a lot of fuss, but I would like to congratulate him on a great career. He has made an outstanding contribution to Welsh rugby.”
