Juan Martin del Potro will be sidelined for an unspecified amount of time after undergoing a minor operation on his troublesome wrist injury.
After 10 months out, the former US Open champion returned to the ATP Tour at the start of 2015 but he was forced to withdraw from the Australian Open after admitting that he didn't feel ready to compete in Melbourne.
However, ahead of day three of the first Grand Slam of the year, the Argentine posted a message on social media to reveal that he could be absent for at least the next few weeks.
The 26-year-old said: "A few hours ago I was in Australia, today at the Mayo Clinic. As recommended by my doctor, I underwent a minor surgery to fix the problem that caused me pain in the wrist.
"I feel more determined than ever to return to the courts sooner than later, to play tennis without feeling pain and to enjoy the love that you give me. I will begin rehabilitation in two weeks. Thanks!!"
Del Potro has dropped down to number 276 in the ATP world rankings.
