“They’re going to operate on me,” he told Argentina’s La Nacion newspaper Friday. The 31-year-old doesn’t know when he’ll have the surgery or who will do it.

Ginobili, who helped lead Argentina to a bronze medal in the Beijing Olympics, said an MRI exam of the injury showed no improvement.

“It’s the same as it was two months ago, when they did the first exam,” he said. “Now, the thing is, it’s not better either, and it seems like the only way to repair it completely is arthroscopic surgery.”

I had arthroscopic surgery on both of my knees while in college, and recovery from those procedures took about a month. But this is Ginobili’s heel, so it might be a different story. He has two months until the season starts, so there is time to recover.
