Argentina have recalled winger Ramiro Moyano among three changes for their Rugby Championship showdown with Australia.
Moyano missed the 35-17 loss to New Zealand last Saturday due to a rib complaint but has been drafted into the 30-man squad for this weekend's clash as a replacement for Bautista Delguy, who will be out for three weeks with a shoulder injury, the Argentine Rugby Union said in a statement.
Coach Mario Ledesma has also included blindside flanker Santiago Grondona in place of the injured Tomas Lezana and winger Manuel Montero for Matias Osadczuk, who was released to play for Argentina's second string side in a tournament in Uruguay.
The Pumas host Australia in Salta on Saturday in the sides' last Rugby Championship match of the season.
Argentina are three points ahead of the Wallabies, who have won only one of their five matches in the competition this season and were surprisingly beaten 23-19 by the South Americans when the teams met in Queensland last month.
New Zealand wrapped up the Rugby Championship title last weekend when they beat the Pumas in Buenos Aires.
The Wallabies take on Argentina in Salta on Sunday October 7 (AEDT) kicking off at 9:40am, LIVE on FOX SPORTS and Channel Ten.
