Alexis Sanchez could be set to miss up to three months with an ankle injury, according to Chile head coach Reinaldo Rueda.
The Inter Milan forward – who is on loan from Manchester United – sustained the injury during the second half of Chile’s draw with Colombia on Saturday.
The Chile Football Federation confirmed that Alexis Sanchez had “dislocated tendons” in his left ankle.
“He could end up under the knife,” Rueda told a news conference.
“Inter, his club, will decide. 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.
“He was happy and super motivated. Now we have to wait for these decisive hours.”
Sanchez joined Antonio Conte’s team on a season-long loan in August and has scored a goal for Inter in four matches, receiving a red card in the same match against Sampdoria.
