International flanker Justin Tipuric and wing Hallam Amos have been included in the Wales Sevens squad that will compete at the Commonwealth Games on the Gold Coast next month.
It was thought 56-times capped Tipuric would not be released by Ospreys, but he is named in coach Gareth Williams' squad.
Amos, 23, has played 15 Tests for Wales but was an unused member of the 2018 Six Nations squad.
Adam Thomas is named as Wales' captain.
Speaking to BBC Wales Sport, Tipuric said: "Through rugby you have a lot of chances to experience things in life and this is another one of them.
"If you can go there and come away with a medal with the boys it will be something that's obviously up there with your rugby highlights."
Dragons, who have not won a league match since September 2017, have four games left this season and Amos will miss at least two matches.
Back-rower James Benjamin is also included in the squad, as is Angus O'Brien.
Scarlets flanker James Davies and newly signed Ospreys back-rower Sam Cross were part of the Team GB squad that won silver at the Rio Olympics in 2016, but will not compete in Australia.
Cross asked not be considered for selection while Williams revealed Davies' absence is due to his Scarlets commitments.
Responding to Davies' absence, Williams told BBC Sport Wales: "He [Davies] has a huge affinity to our squad and we're all very proud of what he's achieved over the past three or four years.
"He's hugely involved at the moment with the Scarlets and especially their Champions Cup quarter-final against La Rochelle and potentially a semi-final which is at the same time as [the Commonwealth Games] Gold Coast.
"With those marquee players from Scarlets and Cardiff Blues, we have left them alone because of European commitments. That's the respect we've built up [with the regions] over the years. We try to make it work as best as we can."
The Commonwealth Games are being held between April 4-15 and Wales are in a group with Fiji, Uganda and Sri Lanka.
