What is Catchweight in the UFC

What is a Catchweight Fight?

A catchweight fight is a term used to describe a bout agreement that occurs at a weight class that does not currently exist in the UFC. Catchweight fights usually occur when there is a late notice replacement that cannot make the weight that the bout is scheduled for.

UFC has a set of different weight classes where fighters typically must be within range of one of them, in order to compete. The one exception occurs when in rare moments a catchweight fight is agreed to by both parties (and the promotion).




A Catchweight Example - Imaginary Scenario

If I am a fighter, and I've been training for 8 weeks to fight at 185 lbs scheduled to fight another fighter, but 3 days before my opponent gets hurt.. The UFC will try to find a last minute opponent for me to fight (as long as I agree to the opponent).

If the UFC ends up finding you, as the last minute opponent that decided to fight me on 3 days notice, BUT you tell the UFC that you can't make the fight at 185 lbs, however you can make 195 lbs.

What will happen is the UFC will come back to me and basically ask "Do you want to fight at 195 lbs in 3 days and receive your full check (and reward your hardwork with a potentially great performance), or do you want to decline this fight and possibly not receive any money (maybe your show money)"

So I as the fighter have a choice to make. I've spent x amount of money on my training camp, food, sparring partners etc for this fight. Do I want to have no fight, or do I want to earn my money and take on a last minute opponent?

Disclaimer: I am not a UFC fighter

Most fighters will choose the option to take the catchweight fight with the opponent, and that is why catchweight fights usually occur.



Why Else Make Catchweight Fights?

Keeping the Competition Honest

In many instances in the history of the UFC, there have been instances where fighters were looking to make superfights, but the size disparity was too great to overcome for one of the fighters to make the weight class, so they proposed a catchweight.




Catchweight Examples

Fights That Did Not Happen

Jon Jones vs Israel Adesanya

These two have created a well documented feud, as they are not each other's biggest fans.

Adesanya is the Middleweight (185 lbs) champion, where as Jones was the Light heavyweight champion (205 lbs) prior to willingly giving it up.

Jones is a natural 230 pounder who cuts down to 205 lbs, whereas Adesanya is a natural 200 pounder who cuts to 185 lbs. Seeing as it's unlikely that Jones would ever be able to make 185 lbs, the only choice is for Adesanya to move up in weight.

You can already see where this is going. If Adesanya moved up to 205 lbs, after weighing in he could be giving up 30-40 lbs to Jones, once Jones rehydrates.

That's a massive size disadvantage and it's one of the reasons why many fans proposed a catchweight fight for the two of them.

Jones ended up giving up his lightweight belt to move up to heavyweight. This fight can still occur at one point, but for now we wait.

GSP vs Khabib

GSP the greatest welterweight (170 lbs) of all time has always been linked to a superfight with Khabib. Khabib's father's dream was for Khabib to retire at 30-0 and beat GSP as well.

Khabib's father's unfortunate death prompted enhanced speculation of this fight taking place, as fans believed that Khabib would want to complete his dad's dream.

As that speculation increased, GSP suggested to fight at a catchweight fight. He pointed out that he was now 39 and hadn't cut weight in 3 years, and Khabib was used to it (cutting weight) at this point, so GSP would be compromising his performance by cutting all of that weight. On top of that, GSP has never cut to 155 lbs in his career.

Khabib on the other hand has fought his entire career at 155 lbs and wanted to finish his career at 155 lbs, as fighting at a catchweight would not count as a title defense.

Both sides made great points. Unfortunately this turned out to be one of the greatest "what if's" as, Khabib ended up retiring in his prime shortly after mauling Justin Gaethje.

Fights That Did Happen

Darren Till vs Stephen Thompson

Till ended up coming 3.5 lbs overweight to the main event in his hometown. Thompson ended up taking 30% of his purse due to the missed weight cut.


Anthony Johnson vs Rich Clementi

Johnson ended up coming at 177 lbs, where Clementi came in at 169 lbs.

Clementi ended up winning in the second round vs a rear naked choke.

Johnson has had a well documented problem cutting weight as he was known to cut up to 50 lbs for a fight. He at one point was even cut from the UFC after coming in 11 lbs overweight to his middleweight bout.

He had a career resurgence once he moved up to a more natural weight class at 205 lbs.

Existing Weight Classes

We've recently created an in-depth UFC weight classes article that covers all weight classes, explains why there are weight classes, life before weight classes, their future, double champions and more.


Which Catchweight Fighter Has the Edge?

This is definitely a case by case basis where there isn't a 'true' answer.

Fightmatrix did a case study on the outcome of fights where a fighter missed weight.

Out of 5,719 fights, the heavier fighter won 54.55% of the time.

As you can see by the data, it's still a toss up on who actually has the advantage. The data tells us that the heavier fighter has a slight advantage, but it's not a clear cut situation.

Is There a Catchweight Champion?

No, as this is an unofficial weight there is no champion. The only champions exists from the existing UFC weightclasses.

Fan Reception of Catchweight Fights

Every once in a while there are two dominant fighters who are a bit far apart in weight. In this case, fans become very interested in the possibility to see two of the best go at it, and also be able to see who would give up a size or weight advantage to prove themselves.

In most other cases, fans acknowledge that a catchweight has been made in order to save a fight to stay on a card. More fights in a card is always great news for fans.

Dana White’s thoughts on catchweight fights

Recently, prior to the bout Conor McGregor and Dustin Poirier had a back and forth where they suggested that their fight should take place at welterweight or even a catchweight bout.

Dana White wasn't too receptive to that when asked by reporters. This was his response "It's 155 pounds," White told BT Sport. "I'm not putting on a freaking multi-million dollar fight at a catch weight that means nothing. … That fight means nothing at 170. Neither one of those two are ranked at 170 pounds and it doesn't do anything in the [155]-pound division if either one of them win cause they're fighting at 170. It literally makes no sense."

So, it's safe to say that Dana White isn't the biggest fans of catchweights, and his track record reinforces that thought as almost all catchweights that are made in the UFC are in order to save a fight with a last minute replacement opponent.

To be fair, it's hard to get a 'casual' fan who doesn't know much about the UFC interested in a pay per view, if there isn't even a belt on the line for the main event.

At the end of the day, the business is about making money while putting on great fights, and those fights need to attract the casual viewers in order to reach their potential.
