A player on Ghana's Under-23 team has tested positive for the novel coronavirus after arriving in Japan for a friendly match, the Japan Football Association (JFA) said on Thursday.
The player had been isolated from the rest of the squad and staff, who are themselves isolated at a designated facility, the JFA said in a statement.
The identity of the player has not been revealed.
The news comes just two days after the JFA cancelled a friendly match against Jamaica as 10 of their players were unable to board a flight to Japan due to coronavirus testing issues.
Japan is battling a fourth wave of COVID-19 just 50 days before the scheduled start of the 2020 Olympic Games, with Tokyo and other regions under a state of emergency until June 20.
The Ghana team arrived late on Wednesday for the friendly against Japan's U24 team in the southern city of Fukuoka.
The team would need health clearance before the match can go ahead as planned on Saturday, the JFA said, adding that it would provide an update when more information was available.
The Ghana squad had left their destination with proof of negative COVID-19 tests within 72 hours of their departure as mandated, the JFA said.
It is suspected that the player contracted the disease on the journey to Japan and there are fears that this could spread among the rest of the squad members who have been isolated.
Ghana failed to qualify for the Olympic Games but will use the test matches to prepare for the next African Games scheduled for Accra in 2023.
The Black Meteors will take on Japan in two friendly matches scheduled for June 4 and 8 in Tokyo before travelling to South Korea to play on June 12 and 15, 2021.
Japan and South Korea will use the two games to test their readiness for the Olympic Games football competition.
