Jason DeLucia (born July 24, 1969) is an American retired mixed martial artist and a pioneer of the early mixed martial arts scene. He competed in the Ultimate Fighting Championship (UFC), Pancrase, and Cage Rage during a career that began in the formative years of modern MMA.
DeLucia entered the inaugural UFC events representing Five Animals Kung Fu, and was one of the competitors at UFC 1, where he served as a reserve fighter and defeated Trent Jenkins in the alternate bout before the main tournament, marking the first match in UFC's history. He subsequently entered the UFC 2 tournament, before losing to Royce Gracie by submission. DeLucia later joined Pancrase in Japan, where he became a prominent competitor and faced many of the leading fighters of the era, including Ken Shamrock, Masakatsu Funaki, Bas Rutten, and Minoru Suzuki. He continued competing internationally for more than a decade, with later appearances in the UFC and Cage Rage Championships.
Mixed Martial Arts career DeLucia began training in martial arts at an early age, developing a background in karate, aikido, Taekwondo and Five Animals Kung Fu, which became his singnature style. In 1992, he drove from Massachusetts to Los Angeles with the intention of answering an open challenge issued by martial artist and actor Steven Seagal published on Black Belt magazine. After the challenge did not materialize, DeLucia learned of the Gracie Challenge and contacted Rorion Gracie, eventually facing Royce Gracie at the Gracie Academy in Torrance, California, in an unsactioned bout. The fight between Royce and DeLucia would later be in one of the Gracie in Action tapes, which inspired the Ultimate Fighting Championship. The experience exposed DeLucia to Brazilian jiu-jitsu and prompted him to begin developing his grappling skills.
DeLucia was invited to UFC 1 by Rorion Gracie as an alternate after his earlier encounter with the family. He was matched against kenpo practitioner Trent Jenkins, a preliminary contest held before the eight-man tournament to determine the tournament's reserve fighter. DeLucia defeated Jenkins by rear-naked choke in 52 seconds. Because none of the tournament competitors withdrew, DeLucia did not enter the main tournament. The bout aired live on pay-per-view but was omitted from the later commercial VHS release, contributing to its later obscurity.
DeLucia returned for UFC 2, now part of the main tournament. On the round of 16, he defeated Wing Chun practitioner Scott Baker, defeating him by submission to strikes from a mounted position after 6:41. He then met Royce Gracie for a rematch at quarter-finals, where he was defeated by an armbar. After DeLucia tapped out, Gracie did not let go of the armbar and the commentator claimed that his elbow had "popped a capsule". However, DeLucia denied this in a Sherdog.com forum, saying it was just badly bent."Q for Jason DeLucia..." . Sherdog Mixed Martial Arts Forums.
After UFC 2, DeLucia met Ken Shamrock and his father Bob Shamrock at the backstage. They were scouting fighters for Pancrase, and DeLucia was invited to train at the Lion's Den. DeLucia recalled that Ken took him to his house, where he lived and trained while preparing for his first Pancrase fight.
DeLucia debuted at Pancrase against its co-founder Masakatsu Funaki, winning by submission to kneebar. He went on to compete in the King of Pancrase tournament in December 1994, one of the first major international MMA tournaments outside the UFC and a showcase for many of the leading fighters of the sport's early era. He defeated Thomas Puckett in the opening round before losing to Minoru Suzuki in the second round. He went on to face many of the organization's leading fighters, including Ken Shamrock, Bas Rutten, Minoru Suzuki, Guy Mezger, Frank Shamrock, and Manabu Yamada, establishing himself as a prominent competitor during Pancrase's formative years. Including three bouts with Rutten, two victories over Ikuhisa Minowa, and a win over Matt Hume. His rivalry with MMA legend Bas Rutten was particularly notable, with DeLucia once suffered a ruptured liver againt Rutten at Pancrase: Truth 6 on June 25, 1996."Q for Jason DeLucia..."

He briefly returned to the UFC at UFC 23, losing to Joe Sleek by TKO.
DeLucia continued competing in Pancrase after his UFC return in 1999, fighting regularly through 2000 and 2001. His final Pancrase bout came on September 30, 2001, when he lost to Katsuhisa Fujii by referee stoppage due to a knee injury during the first round. DeLucia subsequently returned to competition in 2003, defeating Matt Rogers by rear-naked choke in an MMA event promoted by Shootboxing. He later competed in Cage Rage in 2006, defeated by Fábio Piamonte via triangle armbar at Cage Rage 15, and made his final professional appearance that year, losing to Lance Everson at WFL 4.
Post-fight career Following his retirement, DeLucia became increasingly critical of the evolution of mixed martial arts, particularly the widespread use of ground-and-pound. He argued that prolonged ground fighting and strikes from the top position detracted from the submission-focused style of early MMA, which he associated with the rules and philosophy of early Pancrase. DeLucia said he had largely stopped watching modern MMA because of his dislike of ground-and-pound and advocated for rules that would limit the amount of time fighters could remain on the ground while placing greater emphasis on throws and submissions.
During his time in Japan, DeLucia also trained in Pancrase's "Hybrid Wrestling" system and became a certified instructor, later establishing himself as a captain of the Pancrase Hybrid Budokan. He became a promoter of "Hybrid Fighting", a system he developed with Eric Kearns that combined traditional martial arts with elements of modern mixed martial arts. The system emphasized technical competition and safety, deliberately excluding the ground-and-pound techniques that DeLucia had come to criticize in modern MMA.
