Officials are reportedly set to cancel the Miami Open following the cancellation of Indian Wells and President Donald Trump's travel ban.
This week's Indian Wells Masters was the first tennis tournament to be called off because of the virus while the Fed Cup Finals, which were due to take place from 12-19 April in Hungary, as well as the play-offs have also been postponed.
Miami Open officials, though, insisted earlier this week that the event "is moving forward as scheduled" while the official word from the ATP was "the calendar beyond Indian Wells remains status quo".
However, it appears that the Tours will be suspended with Sportsmail reporting "the Miami Open later this month is definitely off, following on from the cancellation of the BNP Paribas Open in Indian Wells".
"But that may lead to a complete suspension of international tennis for the early spring," it added.
"Significant events that could be cancelled include the men's Monte Carlo Open, which begins over Easter weekend, and the WTA tournament in Stuttgart, blowing a large hole in the clay court season.
"According to insiders the plan may extend to stopping all tournaments until the Madrid Open at the start of May, which features the top male and female players."
The second Grand Slam of the year, the French Open, is due to start at the end of May, but officials last week said they had no "postponement of cancellation plans" while Wimbledon is also still "on at present" after the UK government opted not to suspend all sporting events.
However, Sportsmail reports that "while no definitive position has been taken on the French Open and Wimbledon, there will inevitably be fears about their status until the crisis is seen to be in retreat."
