Newport Gwent Dragons player-coach and former Wales captain Colin Charvis has agreed to travel to Tonga for a game to commemorate the coronation of King George Tupou V.
The match, which takes place on July 31, will be contested between a Tongan select XV and a World XV.
The Tonga coronation of King George Tupou V is a showpiece occasion which includes three coronation balls, a military parade, traditional dancing, a fireworks display and an open-air concert, as well as the rugby game.
Charvis - recently appointed as the Dragons contact and defence skills coach - is delighted at the opportunity to take part in the event.
"I'm thrilled that I have been offered the chance to go to Tonga and play a very high standard of game and gauge where I am physically ahead of the season," he said.
"The opportunity has come at a perfect time and I am able to go away and prove my fitness. I would love to continue playing for the region next season as well as fulfilling a coaching role."
