Alexis Sanchez trained with the Chile squad on Tuesday just days after being subbed off for Arsenal.
The 28-year-old attacker sustained an injured ankle early in the first half of Saturday's 3-1 loss to West Bromwich Albion under a heavy challenge from James McClean.
Gunners boss Arsene Wenger said after the game that Alexis' ankle was 'in a terrible state' and that he would only play for his country if there was no ligament damage.
But it appears that Alexis has escaped any major problems as he was able to complete the session with his fellow countrymen in Santiago ahead of the World Cup qualifier with Argentina in Buenos Aires on Thursday and the home clash with Venezuela five days later.
