The Italian won the Monte-Carlo Masters last season but has been dealing with long-standing ankle issues.

The 2020 campaign has been paused since March amid the COVID-19 crisis, but Fognini saw no improvement in his injury problems when he returned to training recently.

Fognini, who broke into the top 10 of the ATP rankings for the first time in 2019, sought medical advice and was set for arthroscopic surgery in Italy on Saturday.

"I've been having a problem with my left ankle for three and a half years now," he wrote to fans on his Twitter page. "It's an issue I've learnt to cope with.

"Then my right ankle started playing up in the past two years as well.

"I had hoped the various issues would go away during the two-month break from the game because of the lockdown, but when I resumed training, they were still there.

"After medical examination and a long discussion with my time, I decided to have arthroscopic surgery on both ankles. I believe it's the right thing to do while the tour is on this enforced break.

"I will undergo surgery in Italy today. I can't wait to be back playing again! I know you will support me. A big hug to all of you!"

The suspension of the ATP Tour has been extended until at least August, with Wimbledon cancelled and the French Open moved to September.

Fognini reached the last 16 of the Australian Open in January but has otherwise struggled for form in 2020, falling at the first hurdle at the ASB Classic, Rotterdam Open and Dubai Tennis Championships.
