Wales have added teenage wing Keelan Giles to their squad for the remainder of the November internationals as a replacement for the injured Hallam Amos.
Giles is considered to be the most exciting prospect in Welsh rugby and the 18-year-old has been outstanding for Ospreys so far in what has been his breakthrough season.
The young flyer was promoted from the Wales Under-20 set-up to tour New Zealand with the senior squad, but was not handed a full international debut.
Giles scored a try on his Ospreys debut against Benetton Treviso after coming off the bench in September and has since claimed two doubles, as well as a hat-trick against Lyon in the European Challenge Cup.
Rob Howley invited Giles to train with Wales at the start of the international season and has now included him in the squad after Amos suffered a shoulder injury in last Saturday's 32-8 defeat by Australia.
Amos, who dislocated his shoulder against England in the Rugby World Cup last September, has been released to return to Newport Gwent Dragons.
Wales face Argentina at the Principality Stadium on Saturday, then take on Japan and South Africa in Cardiff.
