Steve Kerr suffered a spinal fluid leak during his July 28th back surgery on a ruptured disk, which has led to his absence from the team during the preseason.

"I had a spinal fluid leak during the first surgery," Kerr told the media Sunday at the Warriors' practice facility. "It's very rare, it does happen occasionally, but it happens when there's an accidental nick of the dura that surrounds the spinal cord. But I lost spinal fluid, took about a month to figure out what was going on, a lot of headaches, some other symptoms."

After the leak became apparent, Kerr had an additional surgery Sept. 4 to repair the issue.

"The leak is fixed, but still getting some symptoms, but that's why I'm out," he said.

Kerr said he is feeling better, but there's no timetable for his return.

"I wanted to just tell you guys what I'm going through, what's happened. Because I think there's kind of a gray area, people wondering what's going on," he said.
