SAN FRANCISCO — Valkyries coach Natalie Nakase briefly collapsed to the floor during a timeout with 1:40 left in Golden State’s dramatic 77-73 comeback win over the Dallas Wings on Friday night at Chase Center.

After being helped up by her assistant coaches and grabbing her forehead, she returned to the Valkyries’ huddle and drew up the play that led to Gabby Williams’ go-ahead shot that put the Valkyries up 73-72 with 1:17 left.

Nakase remained on the bench to coach the remainder of the game but left shortly after the buzzer sounded under the support and supervision of a team staffer.

“We just tried to step up ourselves,” said Williams, who led the Valkyries with 19 points. “We’re just happy that she’s OK.”

Nakase did not attend the team’s postgame news conference. Assistant Kasib Powell filled in for Nakase postgame and said the coach was “fine.”

“She didn’t miss a beat,” Powell said. “I mean, we were locked in as that happened. When she went to the sideline, she drew the next play up. She was in the huddle, getting on them about getting a stop. So we didn’t skip a beat at all. We tried to keep our composure and just rally around each other and her.”

Powell added, “We just know that we saw her afterwards, and she was fine, laughing, in great spirits. So we’ll figure out more as we go. But I think she’s totally fine. She’s talking. She’s laughing in the back. So we look forward to preparing and getting ready for Sunday.”

The Valkyries were in the final stages of their 16-point comeback when Nakase went to the floor and finished off Dallas with four clutch free throws by Williams.

“I didn’t really see it, but I’m really happy she’s OK,” said guard Tiffany Hayes, who scored 18 points off the bench.

Golden State will face the Las Vegas Aces at 1 p.m. in Game 1 of the WNBA semifinals on Sunday at Chase Center after Golden State’s win in the clinching Game 3.

“I couldn’t tell you (what happened),” Powell said. “I just know that she was locked in right after it happened. After the game, we talked to each other, and it was nothing. I don’t know what got her to that moment or exactly what happened, but we do know that she’ll be ready to go for Sunday.”
