Announced on Thursday, the National Collegiate Athletic Association said its policy applied to all athletes and was effective immediately. The policy change came the day after President Donald Trump signed an executive order preventing transgender women from competing in female categories of sports.

Of the more than 500,000 NCAA student athletes, fewer than 10 of them are trans, according to NCAA President Charlie Baker.

The NCAA updated its policy one day after the administration's order banning transgender athletes from competing on female teams.
