Gabon captain and star player Pierre-Emerick Aubameyang has tested positive for COVID-19 on arrival at the Africa Cup of Nations.
The Arsenal striker was one of three members of the travelling Gabon party to produce a positive result after the team's flight landed in Yaounde.
It means the Premier League star is set to miss his team's opening Group C game against Comoros on Monday.
The Gabon Football Federation issued a statement on its official Facebook page, with a headline of "Aubameyang, Lemina and Yala positive".
The statement read: "Arriving this morning at Yaounde on a special flight, the Panthers of Gabon submitted, like all delegations, to an antigen COVID-19 test at the Nsimalene airport.
"Captain Pierre-Emerick Aubameyang, Mario Lemina and assistant coach Anicet Yala have not escaped [COVID-19].
"But as required by the health protocol in this area, they subsequently underwent a PCR test, the results of which will confirm or deny the status of the latter."
Lemina is another key player for Gabon, with the midfielder having played for Juventus, Southampton, Fulham and now Nice.
Aubameyang missed the start of the Premier League season after testing positive for coronavirus.
More recently, his Arsenal future has become clouded by uncertainty after he was stripped of the club captaincy and dropped by manager Mikel Arteta following a disciplinary breach.
Gabon are also due to face Ghana on January 14 and Morocco four days later.
