Nahuel Tetaz Chapparo has undergone surgery. The Argentine first choice Loose-Head prop will not play again this year.
Having been injured against New Zealand in Buenos Aires Tetaz Chaparro was deemed unfit to face the Wallabies in London. The severity of his shoulder injury subsequently saw his name missing from the upcoming four-match tour of Japan and the U.K.
In place of Tetaz Chaparro Head Coach Daniel Hourcade has three options. Lucas Noguera Paz, who started in London, is the likely leading option. Both Santiago García Botta and the uncapped Facundo Gigena are also on the roster.
