Bayern Munich confirmed that full-back Noussair Mazraoui tested positive for coronavirus during Morocco's historic run to the World Cup semifinals and has since been diagnosed with swelling around his heart. Mazraoui was left out of Bayern's squad that left on Friday for a winter training camp in Qatar before the Bundesliga season resumes on January 20, citing inflammation.
Mazraoui tested positive for COVID-19 during the World Cup in early December, according to the club, and that is why he did not play in
Morocco's quarterfinal win over Portugal.
At the time, his absence was widely attributed to an unspecified illness. Mazraoui returned for the first half of Morocco's semifinal loss to France, as the country became the first African and Arab team to reach the World Cup's last four.
A post-tournament examination in Munich revealed a "mild inflammation," according to Bayern, and Mazraoui is unavailable to play "for the time being." This type of inflammation is a known side effect of COVID-19 infection.
