Nalbandian out for two months
David Nalbandian is set for at least two months on the sidelines as he needs surgery to correct a hernia problem.
The Argentine struggled on through the pain barrier, despite clearly suffering in agony, as he beat Romania's Adrian Ungur in their Davis Cup clash.
Nalbandian, who missed the majority of the 2009 season through injury, suffered the hernia problem initially during the ATP Buenos Aires tournament in February.
The 29-year-old will be hoping to return to tennis in May so he can compete in the French Open, but he admits he was in massive pain due to the problem.
"It was one of the worst moments of my career," he said. "In any other tournament I would have pulled out, but I could not abandon (Argentina).
"It was a horrible experience, but I could not do anything else."
