A high school football coach in Washington state who won his job back after the U.S. Supreme Court ruled he could pray on the field resigned Wednesday after just one game back.

Assistant Bremerton High School coach Joe Kennedy made the announcement on his website, citing several reasons, including that he needed to care for an ailing family member out of state. He had been living full-time in Florida, and before the first game last Friday he said he didn’t know if he’d continue coaching.

“I believe I can best continue to advocate for constitutional freedom and religious liberty by working from outside the school system so that is what I will do,” Kennedy wrote. “I will continue to work to help people understand and embrace the historic ruling at the heart of our case.”
