There is more gender controversy in the world of California volleyball, only this time, it's at the high school level.

Stone Ridge Christian, a central-California high school, has forfeited an upcoming girls volleyball playoff match in protest of a transgender player on opposing San Francisco Waldorf.

The forfeiture comes amid the ongoing controversy surrounding San Jose State's women's team, which has seen a string of opponents forfeit matches to protest the Spartans' Blaire Fleming, a star player who is reportedly transgender.

Stone Ridge Christian administrator Julie Fagundes revealed the decision in a letter to team parents, saying the school has effectively decided to end its volleyball season rather than face a trans opponent. 

'As many of you know, our girls won on Wednesday and advanced to the state playoffs,' read Fagundes' letter. 'Unfortunately, we were just informed that our opponent, San Francisco Waldorf, has a male athlete playing for their team.

'At SRC, we believe God's Word is authoritative and infallible,' she continued. 'It is Truth. And as Genesis makes clear, God wonderfully and immutably created each person as male or female. We do not believe sex is changeable and we do not intend to participate in events that send a different message.'

But the decision to forfeit, thereby bringing the season to an end, was not made strictly on religious grounds, according to Fagundes.

'We also have a duty and responsibility to care for the health and safety of our athletes,' she wrote. 'So after consulting with our students, coaches, and staff, we have made the difficult decision to forfeit Saturday's game.

'Standing for Biblical truth means more than the outcome of a game. This is a heartbreaking end to our season, but I hope you will join me in congratulating these outstanding student-athletes. SRC is proud of them.'
