Less than a week before UFC 232, Jon Jones tested positive for trace amounts of Turinabol. It is the same substance found in his system after UFC 214 in July 2017, which led to a 15-month suspension.
With no ample time to conduct a thorough investigation, the Nevada State Athletic Commission refused to license Jones. This urged the UFC to move the fight from Las Vegas to The Forum in Inglewood, when the California State Athletic Commission decided to license the former light heavyweight champion.
Hours later, USADA released an official statement, trying to shed some light and explain the situation.
