Nick Diaz’s UFC Bans & Walkouts: Dana White’s Explosive Clashes Revealed

**Nick Diaz’s UFC bans and walkouts have become legendary, marking some of the most explosive clashes with Dana White.** The UFC president’s hardline stance on Diaz’s conduct-from suspended fights to public spats-has left a lasting mark on the promotion’s history. Here’s how these incidents unfolded and why they still matter.

Diaz’s first major run-in came in **2015**, when he was suspended for **30 days** after failing a post-fight drug test at UFC 189. But the real turning point was his **walkout at UFC 202** in August 2016. Diaz refused to step into the octagon, citing a contract dispute over pay-per-view revenue. White called it a “disgrace,” and the UFC fined Diaz **$100,000**-a record at the time.

White’s frustration stemmed from Diaz’s **reputation as a loose cannon**. Beyond the walkouts, Diaz’s **pre-fight trash-talking**-often directed at White himself-escalated tensions. In **2017**, Diaz was suspended again after a **public altercation with a fan** outside UFC 214. White later admitted Diaz’s behavior forced the UFC to **tighten its athlete conduct policies**.

The suspensions and fines didn’t just sting financially-they **derailed Diaz’s title shot opportunities**. After UFC 202, he missed **three fights** while serving his suspension, including a prime chance to challenge Conor McGregor for the featherweight title. By **2018**, Diaz was **sidelined for nearly a year** due to a **second drug test failure**, further delaying his comeback.

Diaz returned in **2019** but never fully regained his peak form. His last major UFC bout was at **UFC 254** in October 2020, where he lost to Alexander Volkanovski. Now, with White’s retirement looming, Diaz’s legacy as the **most banned UFC fighter** remains untouched-though rumors persist of a potential **one-off return** for a high-profile matchup.
