Cardiff Blues academy's Callun James is set for his Wales Sevens debut after being selected in the squad for the World Rugby Sevens Series legs in Los Angeles and Vancouver.
The back row is one of four debutants named in Darren Edwards' squad, alongside Ospreys duo Callum Carson and Caine Woolerton and new core player, Alex Gray.
Lloyd Lewis and Ethan Davies return to the fold while core squad members Ben Roach, Jay Jones, Dafydd Smith and Will Thomas have all represented Cardiff Blues at some stage in their careers.
Assistant coach and former Cardiff Blues player, Adam Thomas, said: “We’re back to the normal format this weekend [three games on day one], which will be new to a lot of the squad.
“A few boys have put their hands up this camp, four of whom are in line for their debuts.
“It’s great having Lloyd Lewis here after his time away, and to welcome Ethan Davies back after a long injury lay-off will boost the experience levels of our squad. We’ve got a pivotal weekend ahead at what is the halfway point of the season.”
