Juan Martin del Potro has undergone wrist surgery and is expected to recover "on schedule," said a statement released by his management.
"During the operation, it was discovered that the damage to his wrist ligaments was worse than expected based upon the high resolution imaging obtained before the surgery," said the statement from the Mayo Clinic, where the surgery was performed. "Even so, the surgery went very well and as planned. The damaged ligaments were repaired and reinforced."
The Argentine posted a picture of himself on Facebook after the surgery.
Del Potro's surgeon, Dr. Richard Berger, said, "Given the degree of damage that was discovered in Juan Martin's wrist, it is amazing he was able to play at all."
Del Potro is expected to be out for six months. He underwent a similar procedure on the right wrist in 2010.
