The legend of the organization, Nate Diaz, was displeased with the way someone from Islam Makhachev's team looked at him, which sparked the conflict.
The American initially started verbally provoking Khabib's brothers and then began throwing water bottles at them. Security managed to separate both participants of the dispute, preventing a fight.
It's worth noting that Diaz has not stepped into the octagon since 2022, when he won his last fight against Tony Ferguson.
This Sunday, December 8, another numbered UFC event will take place, featuring a title fight in the flyweight division between Alexandre Pantoja and Kai Asakura as the main event.
