Kevin Durant among four Brooklyn Nets players with coronavirus

Four Brooklyn Nets players have tested positive for the coronavirus, bringing the total to seven known players in the NBA.

The team announced Tuesday that one player is exhibiting symptoms, while the other three are asymptomatic.

All four players have been isolated and are under the care of team physicians.

One of the players was later revealed to be off-season free agent signing Kevin Durant, according to Shams Charania of the Athletic.

“Everyone be careful, take care of yourself and quarantine,” Durant said.

“We're going to get through this.”

The Nets added that all players and members of their travel party are being asked to remain isolated and closely monitor their health.

“The health of our players and staff is of the highest priority to the organization and the team is doing everything within its power to ensure that those affected receive the best care possible,” the Nets added in a statement.

Brooklyn last played on March 10 in Los Angeles, beating the Lakers.

The Nets were then to face the Golden State Warriors two nights later in San Francisco - a game that was to be played without fans - before the NBA season was suspended after Utah's Rudy Gobert tested positive for the COVID-19 virus.

Jazz teammate Donovan Mitchell and Detroit's Christian Wood are the other players who have tested positive.

The Nets said they are currently notifying anyone who has had known contact with the players, including recent opponents, and working closely with state and local health authorities on reporting.

For most people, the coronavirus causes only mild or moderate symptoms, such as fever and cough.

For some, especially older adults and people with existing health problems, it can cause more severe illness, including pneumonia.

The vast majority of people recover from the virus.

NBL forced to cancel remainder of grand final series

The final two games of the NBL's grand final series have been cancelled, with the league still to confirm if a winner will be crowned within the next 48 hours.

Defending champions Perth lead the best-of-five series 2-1 over minor premiers Sydney ahead of the intended game four in Perth on Friday, with the most recent two games played in empty stadiums due to the threat of coronavirus.

The minor premiers informed the NBL they would not travel to Western Australia as planned on Wednesday and The NBL promptly cancelled the best-of-five series, with a decision on which team, if any, claims the trophy in the next 48 hours.

The Kings' decision came as Western Australian health experts called for a state border closure, the club confirming on Wednesday it was a move made with the "well-being of society" in mind.
