5 UFC fighters with siblings who are also fighters

#2. Kamaru Usman and Mohammed Usman

Both Usman brothers are physical specimens unlike any other. Muscled and powerful, Kamaru Usman and Mohammed Usman are imposing figures in the divisions they ply their trades in. 'The Nigerian Nightmare' is the current UFC welterweight champion and is diverging towards cleaning out his division.

Meanwhile, Mohammed Usman is a heavyweight bruiser who recently fought at UFC on ESPN 40, knocking Zaz Pagua unconscious with a left hook that was almost entirely thrown with his arm, there being little hip and back rotation.

The verdict? The younger Usman brother possesses freakish punching power to have secured a knockout without committing most of his body to the left hook.

While Mohammed Usman remains unranked and is a distance away from the kind of legacy his older brother has forged in the welterweight division, the potential promised by his impressive physical attributes will carry higher up the heavyweight rankings in a notoriously shallow weight class.

#1. Nate Diaz and Nick Diaz

No sibling pair is more well-known in UFC history than Nate Diaz and Nick Diaz. While the Shamrock brothers and many others have their place in the halls of MMA legends, Nate Diaz and Nick Diaz are more celebrated by the casual fanbase that vastly outweighs the hardcore MMA audience that still honors the greats of MMA's past.

Prior to his shocking upset win over Conor McGregor at UFC 196, Nate Diaz was the lesser-known Diaz brother as Nick Diaz achieved greater success in the sport due to his past as a Strikeforce welterweight champion as well as his storied rivalry with welterweight legend Georges St-Pierre.

However, when Nate Diaz stepped in on short-notice to face Conor McGregor, the biggest star in MMA history, the results of their bout stunned the world.

Many at the time had declared the matchup a foregone conclusion, with few observers giving the younger Diaz brother a chance at victory. When both men faced off, Nate Diaz raised his guard high, tucked his chin and marched forward, taking away McGregor's preferred counter-striking distance with every step, forcing the Irishman to constantly reset.

While Nate Diaz was bloodied, as is often the case, he eventually seized control of the bout en route to submitting his foe.
