Steve Kerr did not coach during Game 3 of the Warriors' first-round series against the Trail Blazers, and reports late Saturday night indicated he may not return at all during the first round, and possibly longer.

Now, Kerr himself has announced he will indeed be out for Game 4. His return beyond that is still unknown, and will depend on how his back feels.

"I will say this. This is not going to be a case where I'm coaching one night and not coaching the next," Kerr said. "I'm not going to do that to my staff. We're hoping over the next week or two or whatever it is, that I can sort of make a definitive realization or deduction or just feel that I'm going to do this or I'm not."

Everything is up in the air at this point, but there is a possibility that Kerr doesn't come back at all during the postseason.

As Ramona Shelbourne detailed for ESPN a few weeks ago, the problems for Kerr all stem from a failed back surgery after the Warriors won the 2014-15 NBA Championship.

Kerr had back surgery in July, just weeks after Golden State won the 2014-15 NBA championship. The surgery created a fluid leak in his spine, which needed to be repaired by a second surgery in September. In late September, Kerr and Margot had a joint 50th birthday party (their birthdays are a day apart). "He put on a really good face," Margot says. "But you could see he was in a ton of pain."

For months, he was a shell of himself, battling intense pressure headaches and searing pain behind his eyes. The worst of it was not understanding what was wrong or knowing whether it would ever get better. As an athlete, you break a bone and the doctor tells you it will heal in four to six weeks. This was different. Kerr had no answers. It wasn't his back that hurt, it was his head. He felt sick, weak, tired and dizzy. He sat out the first 43 games of the season, leaving 35-year-old assistant coach Luke Walton in charge of the best team in the league.

With so much still unknown about exactly how Kerr is feeling, it's tough to say how this will affect the Warriors. They still have an incredibly talented squad, and should have no trouble getting one more win to get past the Trail Blazers. But beyond that, there's no way to really quantify how much his absence will affect the morale of the team, or their on-court play. 

Hopefully, for Kerr's sake, his status will improve sooner rather than later. If not to the point where he's able to withstand the rigors of coaching, than at least to the point where he's not in so much pain.
