All drug tests in relation to UFC 197, including in- and out-of-competition screens, have come back negative, according to information obtained from the Nevada Athletic Commission (NAC) and UFC vice president of athlete health and performance Jeff Novitzky.
The NAC tested half the card, while USADA tested the rest of the card. USADA handled testing for main event fighters Jon Jones and Ovince Saint Preux. Jones beat Saint Preux unanimous decision to win the UFC interim light heavyweight title.
USADA also tested Demetrious Johnson and Henry Cejudo, who competed in the co-main event.
