Forward Rodrigo Palacio returned to full Argentina World Cup training Tuesday following a sprained ankle and will be fit to face Iran on Saturday.

The 32-year-old Inter Milan striker missed Sunday's 2-1 win over Bosnia-Hercegovina and had not played since twisting his ankle in Argentina's penultimate warm-up, a 3-0 win over Trinidad and Tobago.

Since then he had been subjected to a special training programme to recover.
