Nelson’s record shows the central role of grappling in his career. Thirteen of his 19 professional victories were achieved by submission, while four came by knockout or technical knockout. Only two of his wins required a decision by the judges.
Early martial arts training
Nelson began his martial arts development through karate. This discipline influenced his stance, movement and control of distance. Unlike many conventional mixed martial arts strikers, he often stands with his hands relatively low and uses quick entries rather than relying on a continuous boxing guard.
He later focused on Brazilian jiu-jitsu and submission grappling. His progress was rapid, and he trained under renowned Brazilian jiu-jitsu coach Renzo Gracie. Nelson received a black belt in the discipline and competed against experienced grapplers before becoming widely known through the UFC.
The combination of karate and jiu-jitsu became the foundation of his fighting style. Karate helps him manage distance and create openings, while grappling allows him to control opponents once the fight reaches the ground.
Brazilian jiu-jitsu achievements
Before his UFC career, Nelson established himself as an elite submission grappler. He competed in major international Brazilian jiu-jitsu and no-gi tournaments, gaining experience against opponents from different weight categories.
In 2009, he participated in the prestigious ADCC Submission Fighting World Championship. Despite competing against larger athletes, Nelson reached fourth place in the absolute division. The absolute category has no weight limit, making this result particularly significant for a fighter who later competed at 170 pounds in MMA.
His grappling is based on positional control rather than uncontrolled movement. He is particularly effective at taking the back, maintaining hooks and attacking the neck. The rear-naked choke became one of the most important finishing techniques of his professional career.
Beginning of his MMA career
Nelson made his professional mixed martial arts debut in 2007. His first fight ended in a draw, but he then built an unbeaten record through a combination of submissions and striking finishes.
Before joining the UFC, he competed in several European promotions. His ability to finish opponents and his strong grappling reputation attracted international attention. By the time he signed with the UFC, he was already considered one of Iceland’s most promising combat-sports athletes.
UFC debut
Gunnar Nelson made his UFC debut in September 2012 against DaMarques Johnson. Nelson secured the victory in the first round with a rear-naked choke, immediately demonstrating that his grappling could be effective at the highest level of professional MMA.
He then defeated Jorge Santiago by unanimous decision and submitted Omari Akhmedov with a guillotine choke. A further submission victory over Zak Cummings extended his unbeaten professional run.
Nelson’s early UFC performances established him as a dangerous welterweight contender. Opponents had to be cautious when entering grappling exchanges because a single positional mistake could lead to a submission.
First professional defeat
In October 2014, Nelson faced Rick Story in a five-round main event in Stockholm. Story won by split decision, giving Nelson the first defeat of his professional MMA career.
The fight demonstrated the challenges Nelson could encounter against opponents who maintained pressure, defended takedowns and forced extended striking exchanges. It also provided him with his first experience of completing a five-round UFC contest.
Important UFC victories
Nelson returned from his first loss with several notable performances. In July 2015, he submitted Brandon Thatch with a rear-naked choke after dropping him with strikes. The sequence illustrated how effectively Nelson could move from an accurate striking attack to a grappling finish.
In May 2016, he defeated Albert Tumenov by submission. Tumenov was regarded as a dangerous striker, but Nelson secured control on the ground and finished the fight with a neck crank in the second round.
Another important victory came against Alan Jouban in March 2017. Nelson hurt his opponent with a straight punch and immediately transitioned to a guillotine choke. The finish again showed the connection between his striking and submission skills.
The Bryan Barberena submission
After several years of limited activity, Nelson returned to competition in 2022 and defeated Takashi Sato by unanimous decision. He followed that result with a first-round submission of Bryan Barberena in March 2023.
Nelson controlled Barberena on the ground, advanced into a dominant position and applied an armbar late in the opening round. The victory earned him a performance bonus and confirmed that his submission ability remained effective after a long professional career.
Fight with Kevin Holland
Nelson returned to the Octagon in March 2025 for a welterweight bout against Kevin Holland in London. The fight lasted all three rounds, and Holland won by unanimous decision.
This result moved Nelson’s professional record to 19-6-1. The bout also highlighted the difficulty of closing distance against a taller opponent with a substantial reach advantage and active striking from the outside.
Nelson’s fighting style
Nelson’s approach is unusual because he does not fight at a constant high pace. He often remains patient, waits for his opponent to move and then attacks with a sudden burst. His relaxed stance can make his timing difficult to read.
Several elements define his style:
- a wide karate-influenced stance;
- fast entries from long distance;
- accurate straight punches;
- well-timed trips and takedowns;
- strong control from the mount and back position;
- rear-naked chokes, guillotines and armbars;
- calm decision-making during grappling exchanges.
He does not rely on a large volume of strikes. Instead, he attempts to create a decisive opening that allows him to knock an opponent down, enter a clinch or begin a grappling sequence.
Why his back control is effective
Nelson is particularly dangerous after passing an opponent’s guard or forcing a scramble. He uses balance and body positioning to stay attached while searching for the back.
Once there, he controls the opponent with hooks or a body triangle. The defending fighter must protect the neck while also trying to escape the position. This creates opportunities for Nelson to adjust his grip and apply a rear-naked choke.
His success comes not only from the final submission but also from the positional steps that precede it. He rarely attacks without first establishing control.
UFC submission record
Nelson has earned seven submission victories in the UFC welterweight division. This places him among the division’s leading submission finishers in the promotion’s statistical records.
His UFC submissions include victories over DaMarques Johnson, Omari Akhmedov, Zak Cummings, Brandon Thatch, Albert Tumenov, Alan Jouban and Bryan Barberena. The finishes demonstrate his ability to apply different attacks, although the rear-naked choke remains his signature technique.
Training in Iceland and Ireland
Nelson has trained at Mjölnir, one of Iceland’s best-known martial arts gyms. The facility has played an important role in the development of Icelandic MMA, Brazilian jiu-jitsu and combat sports.
He has also had a long association with Straight Blast Gym Ireland and coach John Kavanagh. Training in Dublin connected Nelson with an international team that included fighters from several divisions and countries.
His friendship and training relationship with Conor McGregor brought additional media attention, particularly during the period when both men were rising through the UFC. Their fighting styles remained different, but both used movement, distance management and unconventional striking positions.
A calm public image
Gunnar Nelson is known for showing little emotion before and after fights. He generally avoids aggressive promotional exchanges and does not rely on personal conflict to attract attention.
This calm image reflects his fighting approach. He appears patient under pressure and rarely wastes movement during grappling exchanges. His reserved personality has become one of the characteristics most closely associated with him.
Importance to Icelandic sport
Iceland has a small population and a limited history in major international MMA organisations. Nelson’s UFC career therefore represented an important milestone for the country’s combat-sports community.
His achievements increased international awareness of Icelandic martial arts and helped demonstrate that athletes from the country could compete at the highest level of MMA and submission grappling.
Nelson’s career also encouraged interest in Brazilian jiu-jitsu in Iceland. His success provided local athletes with a visible example of a path from domestic training to major international competition.
