It’s been 21 years since Nick Diaz’s 10th professional MMA fight.
Nick and his brother Nate Diaz have become two of the most beloved and high-profile figures in mixed martial arts. Fans are drawn to their electric performances inside the cage, while UFC president Dana White often finds himself challenged by their bold behavior during media events.
Known for their fierce competitiveness and sharp tongues, the Diaz brothers have earned reputations as some of the UFC’s best trash-talkers. Their verbal battles haven’t been limited to just before or after fights—they’ve been just as outspoken during the action itself.
A notable example occurred 21 years ago when Nick Diaz engaged in a largely one-sided war of words inside the Octagon.
Nick Diaz disregards John McCarthy’s warnings about abusive language at UFC 51
On February 5, 2005, UFC 51 took place at the Mandalay Bay Events Center in Las Vegas. The event featured Tito Ortiz’s win over Vitor Belfort, with other key victories from fighters like Andrei Arlovski, Pete Sell, and Evan Tanner.
The preliminaries showcased a remarkable showing from Nick Diaz, who bounced back from his first UFC loss with explosive aggression. Diaz defeated Drew Fickett in the first round, delivering a relentless ground-and-pound TKO just 20 seconds before the round ended.
Alongside relentless physical attacks, Fickett also endured a torrent of verbal abuse from Diaz throughout the fight. Referee John McCarthy, positioned nearby, overheard Diaz violating instructions he had given beforehand regarding the use of abusive language.
“I had a fight with Nick Diaz and Drew Fickett, and one of the rules under the uniform code is no abusive language,” McCarthy recalled on the 2024 show Weighing In Progress. “I told Nick in the locker room, ‘You’re going to say certain things, but make sure I’m the only one hearing it. If others hear it, it becomes my problem, so stop it.’”
Despite McCarthy’s directive, Diaz kept calling Fickett derogatory names during the match, ignoring the referee’s pleas to stop. McCarthy later reflected on whether such verbal attacks had a negative impact on the fight itself, ultimately deciding to let it continue.
Nick Diaz and Nate Diaz appear to have patched things up following recent drama
Nick Diaz is planning a UFC comeback in 2026 after facing some challenging years. After being admitted to a rehab facility in Mexico, he was reportedly recently discharged.
Previously, Nick took to social media with posts—since deleted—that seemed to criticize Nate and their close circle. On X, he claimed, “I have been in captivity for over a year, and those who seemed closest kept me there with their own motives.”
He added that “the old man” who claims to represent his family should be discredited, dismissing both him and his allied YouTubers as negative and exploitative. Nick said his circle had grown smaller because of these issues and called out Nate specifically for being a source of embarrassment to their group.
Despite the tension, the brothers were seen together watching UFC 324 in January, signaling their estrangement might finally be over.
Fan Take: The Diaz brothers’ reconciliation is a huge relief for fight fans who have long admired their unique blend of skill and personality. Their return to harmony not only reignites one of MMA’s most compelling stories but could also bring renewed excitement and drama to the sport’s future.
