Blues brothers Nick and Jamie Robinson are joined by Mike Phillips in the Wales team to play in Saturday's first Test against Argentina.
Jamie Robinson will play alongside his younger brother for only the second time in a Test match. The Robinsons became the 28th pair of brothers to play together for Wales when they lined up against Ireland three years ago.
With almost 20 leading players unavailable for the two-Test tour due to injury or rest, Gareth Jenkins first Wales selection shows eight changes from the last Wales game. One of the few survivors from that game Mike Phillips, is paired with fellow Cardiff Blues half back Nick Robinson, which will be their first start together for the national team.
John Yapp and Chris Czekaj will hope to see some game time but start the match amongst the replacements.
