RIO DE JANEIRO, March 16 (Xinhua) -- Flamengo's Portuguese head coach Jorge Jesus has undergone a second coronavirus test to confirm or rule out a positive diagnosis, the Brazilian club said on Monday.

In a statement, Flamengo said the 65-year-old's initial test had delivered an inconclusive result.

The announcement came four days after the club's vice president, Mauricio Gomes de Mattos, was found to have contracted the virus.

All of Flamengo's players and staff were subsequently tested and placed in quarantine. Flamengo said there were no other positive results following the initial tests.

"I'm under the care of Flamengo's doctors and I currently feel well," Jesus said in a video posted on his personal Instagram account. "I had another test and we're waiting for the results. I'm grateful for the messages of support. Thank you."

Former Benfica and Sporting Lisbon manager Jesus joined Flamengo last June and led the club to the Brazilian Serie A-Copa Libertadores double in his first season.  ■
