Wales prop Wyn Jones has been ruled out of the first Test against Argentina on Saturday and will miss the rest of the summer tour.

The 26-year-old suffered a calf injury in training, ending his hopes of winning a 10th cap against the Pumas in San Juan.

“Jones will return to the Scarlets for further diagnosis and prognosis,” said a Welsh Rugby Union statement announcing the news.

Fellow Scarlet Rob Evans will now win his 26th cap after initially being named among the replacements.

Ospreys prop Nicky Smith is promoted to the replacements’ bench.

Wales beat South Africa 22-20 in Washington DC last weekend ahead of their two-Test series against Argentina.
