NSAC

What is the NSAC?

The Nevada State Athletic Commission is a five-member government agency. Nevada’s governor appoints each commissioner to a three-year term, and one of them holds the chairman title. As of 2026, that chairman is Dallas Haun. Jeff Mullen is the executive director, the role that runs the commission’s daily operations.

The commission traces back to 1941, when Nevada’s legislature created it after years of complaints about mismatched fighters, absent doctors, and boxers competing under fake names. Nevada had already legalized prizefighting in 1897, the first state to do so, but formal oversight came decades later.

Because so many major UFC and boxing cards happen in Las Vegas, NSAC’s rulings carry more weight than those of any other state commission. A policy shift here on drug testing or fighter conduct tends to spread to other states within a year or two. Fans run into the acronym for that reason alone.

What the NSAC actually regulates

NSAC’s authority comes from Nevada Revised Statutes Chapter 467, which hands the commission control over every boxing, MMA, and kickboxing contest held in the state. That authority breaks down into a few core jobs.

The commission licenses everyone involved in a fight card. That covers the fighters, their managers, and the promoters staging the event, along with the referees and judges assigned to work it. NSAC also approves the matchups themselves, checks that weight classes and contracts meet state rules, and can block a bout it considers unsafe or mismatched.

On fight night, NSAC oversees the medical side too. Ringside physicians, pre-fight physicals, and post-fight medical suspensions all fall under its watch. It also runs the anti-doping program, testing fighters for banned substances and issuing suspensions or fines for violations, and it can withhold a fighter’s purse until contractual obligations are settled.

NSAC has used that disciplinary power on some of the sport’s biggest names. It suspended Nick Diaz for five years and fined him $165,000 over a 2015 marijuana test, a stance it later reversed almost entirely: in 2024 the commission voted to stop treating cannabis as an anti-doping violation. Conor McGregor was fined $150,000 in 2016 for a bottle-throwing incident before UFC 202, and after the 2018 Khabib-McGregor brawl at UFC 229, NSAC handed out suspensions and fines on both sides of the cage.

NSAC vs. the ABC

People often mix up NSAC with the Association of Boxing Commissions, or assume some single body runs combat sports nationwide. Neither is accurate. The United States has no federal athletic commission for MMA or boxing. Each state runs its own, and the ABC exists to coordinate them, not to license fighters or approve events itself.

	NSAC	ABC
What it is	Nevada’s state regulatory agency	Coordinating association of state and tribal commissions
Licenses fighters	Yes	No
Approves events	Yes, in Nevada only	No
Best known for	Regulating most major UFC and boxing cards in Las Vegas	Drafting the Unified Rules of MMA

Other states run their own versions of NSAC, including the California State Athletic Commission and the New Jersey State Athletic Control Board. All of them work within the same loose ABC framework, but each sets its own suspension lengths, testing rules, and fight-night procedures. A suspension handed down in one state has no automatic effect in another.

Frequently Asked Questions

What does NSAC stand for?

Nevada State Athletic Commission. It’s the government body that licenses and regulates boxing, MMA, and kickboxing events held in Nevada.

Is NSAC the same as the UFC?

No. The UFC is a private fight promotion. NSAC is the state agency that has to approve and oversee any UFC event held in Nevada.

Can NSAC ban a fighter for life?c

Yes. NSAC can suspend a license indefinitely, which bars a fighter from competing in Nevada, though such rulings can be appealed.

Who leads the NSAC in 2026?

Dallas Haun chairs the five-member commission. Jeff Mullen is the executive director, running day-to-day operations.

Does every UFC event follow NSAC rules?

No, only the events actually held in Nevada. A card in another state or country answers to that jurisdiction’s own commission, not NSAC.
