The International Tennis Federation (ITF) said Friday the suspension of professional tennis has been extended until July 31 due to the COVID-19 pandemic.

In April, the Association of Tennis Professionals (ATP) and the Women's Tennis Association (WTA) announced that they were suspending all tournaments until July 13.

On May 15, ATP said it would extend suspensions until the end of July while four WTA events due to be held in July would also be affected.

"Due to continued uncertainties surrounding the COVID-19 pandemic, we regret to announce our decision to extend the suspension of the Tour," ATP Chairman Andrea Gaudenzi said in a statement.

"We continue to assess all of our options in an effort to resume the Tour as soon as it is safe to do so, including the feasibility of rescheduling events later in the season."

The WTA added that it will provide an update in June on the tournaments scheduled for the latter half of July.

The WTA Rogers Cup, which had been scheduled for August 7-16 in Montreal, Canada, had already been postponed to 2021 after Quebec government prohibited holding events until August 31, 2020.
