Verona - Stade Francais flank Mauro Bergamasco has been ruled out of Italy's Test against Argentina on Saturday due to a shoulder injury.
The 31-year-old was injured in training on Tuesday and it was originally thought he would need only a few days rest.
However, Bergamasco, who has 84 Azzurri caps, will continue to undergo physiotherapy, according to the Italian Rugby Federation (FIR), with a view to being available for their next clash against Australia in Florence on November 20.
