Of all the things banned in the UFC, this one sounds the most like a schoolyard dirty trick — and it is genuinely one of the nastier fouls in the rulebook.
It rarely happens, precisely because it’s so reviled. But it has a name, a definition, and a place on the list of things that can get a fighter disqualified.
What Is Fish Hooking In the UFC?
In the UFC, fish hooking is the act of inserting a finger, fingers, or a hand into an opponent’s mouth or nostrils and pulling away from the centreline of the body — stretching and tearing the soft tissue of the face. It’s a listed foul in the Unified Rules of MMA and is completely banned.
The name comes from the obvious image: hooking a finger into the mouth the way a hook catches a fish, then pulling. It is designed to control an opponent’s head or force a reaction through pain, and it can cause real damage to the lips, cheeks and nose.
Why Is Fish Hooking Illegal In the UFC?
Fish hooking is illegal in the UFC because it can tear the mouth, cheeks or nostrils — causing serious, disfiguring soft-tissue injury — while contributing nothing that resembles legitimate technique. It is pure gouging, in the same category as eye gouging and biting.
The face’s soft tissue tears easily. A finger hooked into the corner of the mouth and yanked can rip the cheek; a hand in the nostrils can tear the nose. None of it requires skill, none of it is a martial art, and all of it risks permanent damage — which is exactly the profile of a foul the rules exist to ban.
It sits alongside the other ‘ungentlemanly’ fouls that were prohibited from very early in the sport’s regulation: eye gouging, biting, hair pulling and fish hooking are the classic quartet of things you simply cannot do to another human being, sport or not.
What Is the Penalty for Fish Hooking In the UFC?
In the UFC, fish hooking is penalised like any deliberate foul: a warning at minimum, a point deduction for a clear offence, and disqualification for a flagrant one. Because it is inherently intentional — you cannot hook a finger into someone’s mouth by accident — it tends to be treated harshly when it does occur.
Unlike a low kick that strays into the groin, there is no innocent version of a fish hook. That makes the referee far less likely to extend the benefit of the doubt. A genuine, deliberate fish hook is the kind of foul that gets a fighter disqualified.
What Is the Difference Between Fish Hooking and Eye Gouging?
The difference is the target. Fish hooking attacks the mouth and nostrils, pulling the soft tissue outward. Eye gouging attacks the eyes. Both are gouging fouls that use the fingers to cause pain and damage, and both are banned — but they target different parts of the face.
| Foul | What it targets | The danger |
|---|---|---|
| Fish hooking | Mouth, cheeks, nostrils | Tearing of facial soft tissue |
| Eye gouging | The eyes | Blindness, permanent eye damage |
| Biting | Any body part | Puncture, tearing, infection |
| Hair pulling | The hair | Neck strain, unfair control |
Fish hooking belongs to the classic group of gouging and grabbing fouls banned since the earliest days of MMA regulation.
All four are things that give a fighter control or cause pain without any legitimate technique behind them, which is why they were among the first acts outlawed as the sport became regulated.
Has Anyone Been Disqualified for Fish Hooking In the UFC?
Fish hooking is extremely rare in the UFC, and outright disqualifications for it are essentially unheard of. The foul is so reviled — and so obviously unsporting — that fighters simply do not do it, which is the clearest sign the rule works.
This is true of most of the gouging fouls. Biting, eye gouging and fish hooking are on the books not because they happen constantly, but because the sport needs to be unambiguous that they are never acceptable. The deterrent is doing its job when the foul almost never appears.
Occasional accusations surface in the heat of a scramble — a hand near the face, a fighter complaining — but a clear, deliberate, sanctioned fish hook is one of the rarest things in the sport.
That rarity is itself a kind of testament. In a sport where fighters will exploit every legal edge and push every grey area, the near-total absence of fish hooking says the line is one almost nobody is willing to cross — not because it would not work, but because it sits outside what fighters are willing to do to each other.
Can You Accidentally Fish Hook Someone?
Genuinely accidental fish hooking is very unlikely, because the foul requires deliberately inserting fingers into the mouth or nose and pulling. A hand can brush an opponent’s face in a scramble, but that is not a fish hook — the foul is defined by the insertion and the pull.
This is what separates it from fouls like eye pokes and groin strikes, which are overwhelmingly accidental. There is no common, legitimate action that results in your fingers hooked inside someone’s mouth. The definition itself implies intent, which is why referees treat any real instance seriously.
In the chaos of grappling, hands do end up near faces. But the rule is specific: it is the hooking and pulling that is banned, not incidental contact.
There is a practical reason the distinction matters. Grappling for control of the head is legal and constant — fighters cup the chin, frame on the jaw, and post on the face all the time. The rule has to be narrow enough to allow that legitimate contact while still banning the deliberate insertion of fingers into the mouth or nose. The line it draws is precisely that: hooking and pulling, not touching.

To Conclude
Fish hooking is inserting fingers into an opponent’s mouth or nose and pulling — a gouging foul that can tear the face and has no place in a sport built on technique. It sits with eye gouging, biting and hair pulling among the acts banned from the earliest days of MMA regulation, and it is treated harshly because there is no accidental version of it.
That it almost never happens is the point. The rule exists to make something unambiguous, and the near-total absence of fish hooking in the UFC is the clearest evidence that the message landed.
