Steve Kerr underwent a spinal cord leak procedure on his back and remains out indefinitely.

Kerr hopes having his spine drained will help alleviate the headaches and nausea he has suffered.

"Hopefully the leak was solved; he had another procedure. It's gone on for nearly two years. Very unusual, I believe," Joe Lacob said to Bloomberg Radio. "We feel really bad for him, the players. Everybody understands it. We just have to be in his court here and support whatever it takes for him to get back, and I'm sure they will eventually solve it. Hopefully sooner rather than later, and hopefully we'll have him coaching on the court sooner rather than later."

Mike Brown has served as interim head coach for the Golden State Warriors since Game 3 of their first round series.
