Nate Diaz, Conor McGregor, rest of UFC 196 competitors come back clean in drug tests

Esther Lin, MMA Fighting

Those steroid accusations lobbed around before UFC 196 can be put to rest. So can the curiosity about whether or not Nate Diaz could pass his drug test.

All the drug tests conducted in relation to UFC 196 came back negative, according to the Nevada Athletic Commission and UFC vice president of athlete health and performance Jeff Novitzky. Some of the participants were tested by the NAC and others by USADA, the UFC's anti-doping partner.

In the main event of the card, Diaz defeated Conor McGregor via second-round submission with a rear-naked choke. Before the fight, Diaz accused McGregor -- and everyone in the UFC -- of being on steroids. Diaz has never tested positive for anything before, but his brother Nick is currently serving an 18-month NAC suspension for marijuana. Nick Diaz has popped three separate times for weed in the state.

Miesha Tate beat Holly Holm via fifth-round submission (rear-naked choke) to win the UFC women's bantamweight title in the co-main event.

The NAC tested 18 fighters on the card, while USADA tested the other six, including the competitors in the main and co-main event. Along with in-competition testing, USADA also conducts random, out-of-competition testing throughout the year.

MMA Fighting received the drug test information through a public records request with the commission and confirmation regarding the USADA results from Novitzky.
