The UFC heads to Mexico City this weekend

UFC Fight Night: Brandon Moreno vs. Brandon Royval goes down in Mexico City this weekend. The flyweight main event is a rematch three years in the making with former champ Brandon Moreno taking on the man he beat at UFC 255, Brandon Royval.

November 20, 2020, Las Vegas, Nevada, Las Vegas, NV, United States: LAS VEGAS, NV - NOVEMBER 20: Brandon Moreno and Brandon Royval face off during the UFC 255 weigh-ins at UFC Apex on November 20, 2020 in Las Vegas, Nevada, United States.

The co-main is another rematch, with Brian Ortega hoping to exact revenge on Yair Rodriguez. The card also features Raul Rosas Jr. vs. Ricky Turcious and Yazmin Jauregui vs. Sam Hughes.

According to MMA Fighting, these fighters (and everyone else on the card) will need to be extra vigilant when competing in Mexico.

That outlet reported that fighters at UFC Fight Night: Moreno vs. Royval will be subject to both the UFC’s own drug testing policy and the policies of the Mexican MMA Federation. And it sounds as if the local commission will have much stricter guidelines than the UFC’s own, and somewhat mysterious, protocols.

According to the report fighters will be subject to a zero tolerance policy on a number of banned substances. This means that any amount of those drugs found in a fighter’s system will equate a drug test failure.

List of substances

The UFC recently sent a guideline out to their Mexico City card athletes instructing them when to abstain from specific substances. That guideline also warned that there must be “zero presence” of these substances on weigh-in day and fight day.
