Chile manager Reinaldo Rueda said on Monday that Alexis Sanchez may need to undergo surgery and could miss up to three months of action after suffering an ankle injury against Colombia on Saturday.
Rueda told reporters that Sanchez's club side, Inter Milan, will now decide how best to proceed with the forward, who joined the club on a season-long loan from Manchester United in August.
"He could end up under the knife. Inter, his club, will decide," he said. "We could lose him for two or three months. It's a shame because he had started playing again with Inter and scored two goals while also playing in the Champions League.
