Juan Martin del Potro has suffered another major injury blow after revealing he requires a fourth operation on his knee.
The Argentinian has not played since Queens 2019 when he fractured his knee cap for the second time in eight months.
He has been attempted to return to the ATP Tour since, and has made no secret of the fact he wants to play the Olympics.
Those Olympic hopes, he says, are still alive, with del Potro sending a message of defiance alongside the news.
"I wanted to say hello and tell you I’m currently in Chicago," del Potro said on Instagram.
"I’ve been consulting Dr. Jorge Chahla and the news is that tomorrow I’ll undergo another surgery on my knee.
“We’ve tried conservative therapy but the pain is still there. He knows I want to play tennis again and be able to play the Olympics, so we agreed that surgery should be done as soon as possible."
It's been a tough year for Juan Martin del Potro after he lost his father as well, but he says that is actually giving him the strength to keep going.
“Of course, these last few weeks weren’t easy for me," he said. "Everything’s so hard since my father’s passing.
"But also, I feel the strength he sends me from above. I had this day in which I woke up and called the doctor. I knew I had to try again.
“I hope I can overcome this painful situation. I won’t stop trying."
