Christopher Humm, a spokesman for the university's athletic department, said Digit Murphy is "pursuing other opportunities."

According to the Brown women's hockey website, Murphy became the coach with the most wins in Division I women's hockey history during the 2006-2007 season. Over two decades, she led the team to five Ivy League titles and several national championship appearances. Seven of her players have played in the Olympics for the United States, Canada and Japan.

Murphy could not immediately be reached. A message left for Michael Goldberger, Brown's director of athletics, was not immediately returned.

Brown has the oldest women's hockey team in the country.
