Chile captain Alexis Sanchez has been released from the squad to undergo further tests after suffering a left ankle injury in La Roja's friendly draw with Colombia on Saturday.
The Chile FA confirmed that Sanchez suffered "dislocation of tendons in the left ankle" during the 0-0 draw in Alicante, Spain, and will return to Milan to undergo an MRI. He will miss Chile's friendly match against Guinea on Tuesday.
Sanchez is at Inter on loan from Manchester United after a disappointing spell at Old Trafford, with Inter on the hook for £175,000 of his £390,000-a-week salary. He has scored one goal in four appearances across all competitions for the Serie A side this season.
Chile also said that Bologna midfielder Gary Medel suffered a right foot injury and will also miss the match against Guinea.
