Nick Diaz was born and raised in Stockton, California and is of Mexican descent. Diaz is the older brother of UFC fighter Nate Diaz and went to Tokay High School in Lodi, California for a year before dropping out. While a freshman, he was a member of the swim team. Diaz has stated in the past that he is thankful his mother got him into swimming classes because it is one of the main reasons why his cardio is so impressive during his fights. He has also said on multiple occasions that he had a hard childhood, and grew up without his biological father. Diaz started practicing karate and aikido around the age of 14 and also participated in wrestling tournaments. Diaz originally started training in martial arts because he was being bullied by other teenagers who were bigger than he was. He then watched the UFC for the first time and soon wanted to be able to fight in the organization. His younger brother, Nathan is also a professional MMA fighter in the Lightweight division and the winner of The Ultimate Fighter 5. Nick also regularly competes in triathlons as part of his training. Diaz started training in Sambo at the age of 16 under a Bulgarian National Sambo Champion Val Ignatov. In his recent interview with Ariel Helwani, Diaz stated that he still trains Sambo under the same coach hence the reason his ground game is different from other MMA fighters that only train in Brazilian jiu-jitsu. Diaz was promoted to black belt in Brazilian jiu-jitsu by Cesar Gracie on May 8, 2007. Diaz currently teaches Brazilian jiu-jitsu at his and brother Nathan’s school in Lodi, California.
After years of practicing various combat sports and martial arts, Diaz became a professional mixed martial arts fighter in 2001 just after his 18th birthday and winning his first fight, submitting Mike Wick with a triangle choke at IFC Warriors Challenge 15. Diaz would become a champion in just his second professional fight, defeating Chris Lytle for the IFC Welterweight Championship in July 2002 at IFC Warriors Challenge 17. Diaz was then invited to participate in Ultimate Athlete’s King of the Mountain, a single-night tournament that took place two months later. He won his first two fights but eventually lost in the finals to Jeremy Jackson by TKO. Diaz would fight in Warriors Quest and Shooto against Harris “Hitman” Sarmiento and Kuniyoshi Hironaka respectively before defending his IFC Welterweight Championship and winning the WEC Welterweight Championship in 2003 at WEC 6, submitting Joe Hurley with a kimura. Diaz returned to defend his IFC Welterweight Championship against the man who defeated him one year earlier, Jeremy Jackson at IFC Warriors Challenge 18. This bout was for Diaz’ IFC United States Welterweight Championship, Jackson’s IFC Americas Welterweight Championship and the vacant ISKA-MMA Americas Welterweight Championship. Diaz won the rematch via TKO in the first round. Taking notice of his success, the UFC signed Diaz over the summer and he made his debut at UFC 44, completing the trilogy against Jackson and submitting him with an armbar in the last round of a back-and-forth fight that Diaz appeared to be winning on the scorecards. Diaz returned to the Octagon at UFC 47, set to take on highly touted future EliteXC Middleweight Champion Robbie Lawler. Lawler was a heavy favorite coming into the fight but it was Diaz who took the offensive, chasing Lawler around the cage for the majority of the bout. In the second round, Diaz taunted Lawler, who swung wildly and missed, allowing Diaz to connect with a right hook that knocked Lawler out. Diaz was then matched up with judoka Karo Parisyan at UFC 49, but ended up losing a hard-fought split decision. He rebounded with wins over submission specialist Drew Fickett at UFC 51 and Koji Oishi at UFC 53 before losing for the second time in the UFC at the hands of The Ultimate Fighter Middleweight winner Diego Sanchez at The Ultimate Fighter 2 Finale.
Diaz was confident coming into the bout but was unable to achieve success in the match, ultimately losing to Sanchez by unanimous decision. During the televised post-fight interview in the ring, Diaz continued the controversy by declaring that he respected Sanchez fighting ability but did not think he deserved to be there, despite Sanchez’s win. Diaz’s next fight was against Joe Riggs at UFC 57. Similar to his treatment of Sanchez, Diaz made sure that he taunted his opponent plenty before their fight starting at the official press conference at the event in which Diaz confronted Riggs and the two exchanged words. They continued their conversation at the official weigh-ins in which both fighters had to be separated by UFC president Dana White and other officials present. Riggs prevailed in a hard-fought battle, winning by unanimous decision and giving Diaz his second straight loss. After the fight, the two were taken to the hospital for observation and post-fight tests. Diaz lost his third consecutive match in a unanimous decision to future UFC Lightweight Champion Sean Sherk at UFC 59. The UFC subsequently terminated his contract and released him during the spring of 2006. UFC president Dana White stated that a matchup between Diaz and UFC Welterweight Champion Georges St-Pierre was a possible consideration. Diaz and St-Pierre were rumored to be the next coaches for The Ultimate Fighter 14 reality show, but the show debuted on September 21, 2011, with Michael Bisping and Jason Miller as coaches. White later confirmed via Twitter that Diaz would face St-Pierre at UFC 137 at the Mandalay Bay Event Center in Las Vegas, Nevada, on October 29, 2011. Nick Diaz vacated his Strikeforce Welterweight Championship title prior to his bout with Georges St-Pierre.Dana White made the decision to take Diaz out of the fight and replace him with former WEC Welterweight Champion and future UFC Interim Welterweight Champion Carlos Condit, due to Diaz missing multiple flights for a press event to support the fight.It was announced that Diaz would fight B.J. Penn in the main event at his original fight card, UFC 137. Diaz won via unanimous decision. Diaz called out St. Pierre in the post-fight interview, who was scheduled to fight Condit at the same event but had been forced out of the bout with a knee injury. Following his successful return, Diaz was expected to face Georges St. Pierre for the UFC Welterweight Championship at UFC 143 during Super Bowl weekend. However, due to an ACL injury sustained by St-Pierre, Diaz faced Carlos Condit in the main event, with the winner being awarded an Interim UFC Welterweight Championship. Condit defeated Diaz via unanimous decision. Upset with the result of the fight, Diaz indicated that he was retiring from the sport. After the event UFC President Dana White said that he believes Diaz will fight again. Diaz was briefly linked to a rematch with Condit, but was quickly refuted when Diaz tested positive for marijuana metabolites in a post-fight drug test. The Nevada State Athletic Commission temporarily suspended Diaz shortly after the positive test, pending a full disciplinary hearing. It was announced at the hearing in May 2012 that Diaz was suspended for one year, retroactive to February 4, 2012, and fined 30 percent of his fight purse earned from the Condit bout. Diaz was eligible to return to MMA competition in February 2013. Diaz faced Georges St-Pierre at UFC 158 on March 16, 2013 for the UFC Welterweight Championship, losing via unanimous decision. Before leaving the octagon, Diaz once again expressed interest in retirement. As of July 28, 2013, Diaz is retired from MMA fighting. However in previous interviews, Dana White has since explained that Diaz has money to relax from the GSP fight, but does expect him to return eventually. A possible Middleweight matchup between Michael Bisping and Nick Diaz was briefly linked, but soon turned down by Diaz.
