Cape Town - South Africa's Kevin Anderson could be sidelined for several months after undergoing knee surgery.
Anderson has endured a frustrating time of late, having also missed the second half of 2019 due to injury.
The 33-year-old, who has now fallen to a ranking of 121st, crashed out of the opening round of the New York Open last week.
Anderson revealed on Twitter on Friday that he underwent a successful procedure on his right knee.
"Midway through December last year, during my off season training, I injured my right knee," wrote Anderson.
"I tried to push through in training on both on the match court, but it didn't get better. I had scans done in Australia, and they unfortunately showed that I had suffered a medical meniscus tear. After consulting with medical professionals and my team, we decided that having surgery was the best way forward. I had the procedure on Wednesday."
Anderson added his frustration over being on the sidelines again, but believes that he'll be back on the court soon.
"It is beyond difficult and frustrating to have to deal with this, after the setbacks I had last year. But I know it's the right decision for me to get back where I want to and rest assured, I will do everything in my power to get there," he continued.
"... I look forward to seeing you back out there as soon as possible."
There's no specific mention on how long the South African will be out for, but he joins Roger Federer, who also underwent knee surgery and is expected to be out until June, on the sidelines.
