Injury blow for Pumas
Argentina have injury concerns of their own ahead of their clash with Australia in Rosario this weekend.
Argentina fullback Martin Rodriguez is to undergo an operation on a shoulder he dislocated in their 54-15 loss to New Zealand in the Rugby Championship at the weekend.
Rodriguez, who plays his club rugby for Top 14 outfit Stade Francais, will go under the knife in the "coming days", Argentina's rugby federation said.
The 27-year-old, capped 19 times, will miss the Pumas' final run-out in the Championships against Australia on Saturday as well as the November internationals against Wales, France and Ireland.
