Flamengo manager Jorge Jesus has tested positive for coronavirus.
The 65-year-old took charge of the Brazilian side last summer, and has since led Flamengo to the final of the FIFA Club World Cup where they were defeated 1-0 by Liverpool.
According to AS, Jesus and vice president Mauricio Gomes de Mattos both tested positive for the virus, but the former will undergo a second test due to inconclusive results.
The report also states that Flamengo's players are in quarantine following Gomes de Mattos' diagnosis, while the remainder of their staff are self-isolating as a precautionary measure.
The 2020 Brazilian Serie A season is due to start on May 3.
