The return of Steve Kerr to the Golden State Warriors’ bench remains uncertain, but he might be closer to having a resolution of the agonizing back pain that has sidelined him for five playoff games and counting.

Kerr has suffered from the debilitating effects of a cerebrospinal fluid leak, a consequence of back surgery nearly two years ago. A second procedure to correct that in October 2015 failed, and Kerr had sought alternative answers for his pain until stepping away April 24. After seeking more medical opinions, he underwent further treatment.

“Hopefully the leak was solved; he had another procedure. It’s gone on for nearly two years. Very unusual, I believe,” Joseph Lacob, the Warriors’ majority owner, said Friday on 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.”

Kerr did not travel with the Warriors to Utah, where they took a 3-0 lead in a Western Conference second-round playoff series with a victory Saturday night. In the recent news conference in which he announced that he was not certain when he could return, Kerr advised people with back problems to “rehab, rehab, rehab” rather than having surgery but added that, in his case, intensifying symptoms could help doctors pinpoint the source of his problems. According to multiple reports, he was examined by doctors at Stanford and Duke.

“That’s what the next few days are all about,” Kerr said in April. “They’re trying to find it. If they can find it, they can fix it.”

Kerr missed the first 43 games of the 2015-16 season after having two back surgeries. Luke Walton, now the Los Angeles Lakers’ coach, took his place then, and Mike Brown is subbing for him now.
