Juventus midfielder Arturo Vidal is struggling with a knee injury, admits Chile coach Jorge Sampaoli.
The midfielder played the full 90 minutes for Chile beat Peru 3-0 in a friendly.
"Arturo finished the game with pain in his knee tendon and we'll see what to do after tests," Sampaoli told reporters.
It is therefore likely Vidal will be sent home rather than play in Tuesday's game against Bolivia.
"Peru did not come here to play a friendly, as it was a tough and intense match."
