(Reuters) - Golden State coach Steve Kerr’s spinal cord leak procedure went well, the team’s General Manager Bob Myers said on Sunday, but there is no timeline for his return.

Kerr, 51, first hurt his back during the 2015 NBA Finals, and subsequent surgeries and associated pain kept him sidelined for the first 43 games of last season.

The pain and headaches returned after Game 2 of the Warriors’ first-round matchup against the Portland Trail Blazers last month, and assistant coach Mike Brown has filled in during his absence.

“He was at Duke, he had the procedure done Friday,” Myers told reporters in Salt Lake City on Sunday, where the Warriors currently hold a 3-0 lead over the Utah Jazz in the best-of-seven series.

“Even the doctors aren’t entirely sure of recovery time and that’s why we’ve been a little indefinite about everything. We don’t know. But the procedure went well as far as we know,” he said.

“Now it’s a case of how it takes and when he might or might not be back. The good news is it’s on the path to recovery. I wish I could be more definitive.”

The Warriors will look to improve their 2017 postseason record to 8-0 when they play the Jazz on Monday.
