Next week's Hero Indian Open and August's Czech Masters have joined this week's Kenya Open and April's Maybank Championship and China Open in falling victim to concerns over the spread of Covid-19.

With no regular European Tour events scheduled in the fortnight before The Masters, it means an eight-week gap between the staging of the Qatar Masters in Doha and the next regular event in Spain.

The Andalucia Masters is currently scheduled to be held from April 30-March 3 at Valderrama, Spain.

The reduction in the number of tournaments could have a significant impact on qualifying for other events, most notably the Ryder Cup, as well as the Race to Dubai standings which determine which players keep their card for next season.

In a statement, a spokesperson for the European Tour said: "We are currently reviewing all aspects of the wider competitive impact of tournament postponements."

Three Challenge Tour events run by the organisers of the Czech Masters have also been cancelled.
