Alexis Sanchez faces up to two months on the sidelines, according to Chile national team doctor Pedro Onate, who examined the knee injury that the forward sustained in Manchester Unitedโs win over Southampton.
The former Arsenal man was replaced after 52 minutes of the 3-2 victory at Old Trafford, following a challenge from Saints defender Jan Bednarek, and Unitedโs own medical staff have yet to provide a prognosis.
But Onate said that an examination of the wingerโs condition showed he had suffered distention of the medial ligament, which would take a number of weeks to heal.
Onate told El Mercurio: โThere wonโt be any problems for him to be at the Copa [America], because heโll be out for between six and eight weeks.
โAlexis may even play again before that time. Plus, thereโs a long way to go until the Copa America.
โThe distention of the medial ligament is an annoying injury, but itโs not so complex.โ
United will be without Sanchez as they travel to Paris Saint-Germain for the second leg of their Champions League last 16 tie on Wednesday, where they hope to overturn a 2-0 deficit.
Sanchez has made just eight Premier League starts for the club in 2018-19, scoring once.
