Argentina's Ezequiel Garay could miss the Copa America final due to a stomach problem.
The Zenit St Petersburg defender missed the 6-1 thrashing of Paraguay after complaining of feeling unwell, and he is still battling to prove his fitness in time to be considered for selection against Chile.
Garay missed Wednesday's training session before being forced to work away from his teammates on Thursday as Argentina continue their preparations for Saturday's game in Santiago.
The 14-time Copa winners can match Uruguay's record for the most wins in the tournament by beating the hosts.
