2009 U.S Open champion Juan Martin Del Potro, who has not played on tour since Australian Open this year, will undergo a surgery on his right wrist.

“I have tried all season to avoid surgery by trying different treatments but, evidently, the injury was more serious." said del Potro.

He added “This is not a happy moment in my life. But I’m used to battling through adversity and I have the strength to come through this. The recovery time will be lengthy, but it depends on many factors that today I can’t assess because it’s too soon."

The Argentine said that he was likely to be out for "a long period" and said previous treatments had not solved the problem.

“I will spend the first few days after the operation in Rochester and then I will return to Argentina where, with more precision, I will be able to explain each step of my recovery.”
