UFC Career

The 2019 debut isn't in our fight list, but the next fight is: a unanimous decision over Daniel Spitz in October 2019. Two months later he took a unanimous decision loss to Ciryl Gane.

2020 was the best stretch of his run. Philipe Lins went down by TKO in the first round at 2:41, and Raphael Pessoa followed a month later by second-round TKO. That's his longest streak, two wins, both stoppages. A unanimous decision loss to Andrei Arlovski ended it.

A split decision loss to Ilir Latifi came next, then a second-round TKO of Ovince Saint Preux three weeks later in June 2021. In September 2022 he dropped another split decision, to Rodrigo Nascimento.

Two knockout losses sit in the middle of the run. Ion Cutelaba stopped him in the first round at 2:05 in April 2023. In April 2026, Gokhan Saricam finished him in the second round at 4:43. In between, he beat Aleksa Camur by unanimous decision in August 2023.

The latest result is the best one on the list: a third-round TKO of Jhonata Diniz at 4:26 in October 2026.

Close fights haven't gone his way. Three of his four decision losses, if you count the splits as the tight ones, were that close.

Fighting Style

Tanner Boser is a busy, accurate striker who is hard to stop on the mat. He lands more than most and connects at a better rate than the UFC average, and he is tough to take down.

One note on his defense: he absorbs far more strikes than most fighters, so he takes damage while he trades. His takedown defense is the standout, as opponents have a hard time putting him on his back.

He rarely shoots for takedowns and rarely hunts submissions, and none of his wins came by submission. His offense is built on striking.

The finishing pattern is clear. All four stoppage wins are TKOs: one in round one, two in round two, one in round three. Two of his losses came by stoppage as well. When a fight doesn't end early, it tends to go to the judges, and his record there is two wins against four losses.
