Image source, Huw Evans Picture AgencySteve Tandy named three uncapped players in his initial squad - centre Aneurin Owen and scrum-half Che Hope from Dragons plus Cardiff loose-head prop Rhys Barratt.
The trio were then joined by in-form Scarlets wing Macs Page after Rio Dyer suffered a hamstring injury before joining up with the squad.
All four players will watch on from the stands today after missing out on the matchday 23.
Will they get a chance against New Zealand, Australia or at Twickenham?
Barratt has pulled on the red jersey before against Barbarians last summer in an uncapped fixture.
