Chile coach Juan Antonio Pizzi expects to have midfielder Arturo Vidal available for his side's friendly against Mexico.
Pizzi's men suffered a shock 2-1 loss to Jamaica on Friday and they complete their Copa America Centenario preparations with Wednesday's friendly in San Diego.
"We believe that Marcelo Diaz and Arturo Vidal will be available for the match against Mexico and from that we set up the team," he said after the Jamaica loss.
"Our preparation is logically focused on the match with Argentina [at the Copa on June 6]."
"The list of 23 players were chosen because we believe they can contribute," he said.
"We believe the level of the players we have, leaving me calm that they are good players.
"Time will define the performances that everyone has."
Juan Carlos Osorio's side are unbeaten in 18 matches, dating back to last year's edition of the Copa America.
An Andres Guardado goal helped Mexico to their latest win – a 1-0 victory over Paraguay on Saturday.
He was pleased with his side's display against Paraguay, arguably their greatest test yet under his guidance.
"We believe that the game gives us a positive balance," Osorio said.
"We faced an opponent with a lot of history, with more physical training than us and managed to go ahead."
