Bayern Munich defender Alphonso Davies has stopped training after the club detected signs of heart muscle inflammation.
The Canadian, 21, has not played since December 17 after contracting the Covid-19.
Bayern boss Julian Nagelsmann said a slight sign of myocarditis was discovered after Davies returned to training.
“During our follow-up exam that we do with each player who has had Covid-19, we detected signs of mild myocarditis,” Nagelsmann said.
“He has stopped training for the moment, so he will not be available to us for the next few weeks.”
Myocarditis is an inflammation of the heart muscle that can reduce the heart’s ability to pump blood and can cause fast or irregular heart rhythms.
Davies has made 107 appearances for Bayern since signing from the Vancouver Whitecaps in 2018, helping them win three Bundesliga titles and the Champions League in 2020.
“This myocarditis is not too dramatic from the ultrasound, but more simply signs of inflammation. Nonetheless, it needs healing and it will probably take some time,” Nagelsmann said.
On January 5, Bayern said Davies was doing “well” after testing positive for Covid.
Nine Bayern players tested positive in early January after an absence after the winter break from the Bundesliga.
