Figallo answers Pumas SOS

Chaparro is out for the remainder of the tournament, after tearing his femoral biceps in training after making two appearances.

Figallo, the 27-year-old Salta-born prop, has earned 22 caps and scored one try for Argentina.

He was part of the pre-selection squad ahead of the tournament, but was cut from the final 31 due to a knee injury.

His most recent international was the 33-15 defeat by New Zealand in The Rugby Championship at La Plata, Argentina, on September 28, 2013.

The Saracens player joined the Argentina squad on Thursday.
