Manchester United attacker Alexis Sanchez could be sidelined "for the next six to eight weeks" with the knee injury that he picked up against Southampton on Saturday afternoon.
Sanchez was forced off in the second half of United's 3-2 win over the Saints at Old Trafford.
According to Pedro Onate, who is a physiotherapist with the Chile national team, Sanchez could be on the sidelines for the next two months, forcing him to miss a whole host of important matches.
"We spoke with him [on Sunday] and he had the tests and that's the injury. There will be no problems for him to be fit for the Copa America because he won't be playing for six to eight weeks," Onate told El Mercurio.
"But Alexis may return before those deadlines. The medial ligament distension is a troublesome injury, but not so complex."
Sanchez has struggled to produce his best form since joining United from Arsenal in January 2018.
This season, the 30-year-old has only managed two goals in 23 appearances in all competitions for the Red Devils.
