Bayern Munich left back Alphonso Davies has been sidelined with evidence of heart muscle inflammation after being infected with the coronavirus, coach Julian Nagelsmann said Friday.

The Canada international will be out of action for at least “the coming weeks” after the inflammation, known as myocarditis, was detected in a follow-up examination after his return to training this week, Nagelsmann said. The coach described the inflammation as “mild” and “not so dramatic,” citing the results of an ultrasound examination.

“Despite that, it needs to heal and that will definitely take a certain amount of time,” Nagelsmann said.

Myocarditis is a mild, temporary condition in the vast majority of cases, according to experts.

Bayern said last week that Davies had tested positive and he was back in training on Wednesday. Nagelsmann said Davies would now stop training until further notice to give his body time to recover.

Canada Soccer confirmed on Friday that Davies won't be available for Canada's next three World Cup qualifying games in late January and early February, including a game against the United States on Jan. 30. Canada leads qualifying in CONCACAF as it tries to reach its first World Cup since 1986.

Bayern leads the Bundesliga and plays Cologne on Saturday.

Gabon and Arsenal forward Pierre-Emerick Aubameyang has been diagnosed with heart lesions at the African Cup of Nations in Cameroon after contracting the coronavirus, the Gabon Football Federation said on Friday.

It ruled Aubameyang out of Friday's game against Ghana and put the rest of his African Cup in doubt.

The “cardiac lesions” were found in a check by Confederation of African Football medical officials, who examined Aubameyang to ensure he was OK to play again after he returned from a positive virus test, the Gabon federation said in a statement.

Two other Gabon players were also prevented from playing after similar medical checks following their return from positive virus tests.

The Gabon federation said Aubameyang's diagnosis wasn't serious but the medical officials “did not want to take any risks,” and CAF's medical commission ruled Aubameyang was not able to play against Ghana. A lesion is damage or abnormal change to body tissue.

Aubameyang tested positive for the virus at an airport on arrival in Cameroon last week and was put into isolation. He also missed Gabon's first game, a 1-0 win over Comoros.

The Gabon captain has since tested negative for the virus and was out of isolation two days before the Ghana game and was expected to return to the team.

Gabon forward Axel Meyé and midfielder Mario Lemina were the other two CAF prevented from playing against Ghana after they also had evidence of cardiac lesions, the Gabon federation said. They had also been isolating because of positive virus tests.
