The women’s volleyball team at the center of a national debate over gender and sports advanced to the conference championship after Boise State refused to play.

San Jose State University said it was “disappointed” after Boise State dropped out of the end-of-season women’s volleyball championship rather than play the Spartans, whose team features a biological male.

Twice during the regular season, the Boise State women’s volleyball team took a moral stand by forfeiting matches against San Jose State rather than competing against a player believed to be transgender.
