Thomas Petersen brings a 3-3 UFC record to Abu Dhabi, with his fights contested at heavyweight. He debuted Feb. 3, 2024. His most recent five bouts have alternated between wins and losses. Petersen beat Mohammed Usman by unanimous decision July 20, 2024, then was stopped by Shamil Gaziev via first-round TKO on Feb. 1, 2025. He rebounded May 3, 2025, with a unanimous decision over Don'Tale Mayes, before Vitor Petrino stopped him by third-round TKO on Oct. 11, 2025.

The facts, plainly — vitals and record from public UFC statistics; nickname, nationality, hometown and camp from the public fighter register. A field we can't source stays “pending”; it never shows a fake value.

Where the strikes go — and where they land on him. Career UFC totals, straight off the tape.
Significant strikes only, as recorded by UFCStats, across the fighter's whole UFC career. Shares are raw counts — nothing here is modelled or smoothed. Accuracy is landed ÷ attempted and comes from the per-round tape, which covers slightly fewer fights than the totals do. “Field” is the average fighter in that weight class, or across every division where a class is too small to average.
The level change — how often it lands, how often it is stopped. Career UFC rates, straight off the tape.
Rate bars run to the population’s 95th percentile (5.77 takedowns / 15m); a fighter above it pins the bar. Percentages are drawn on their own axis.
Career UFC takedown rates exactly as UFCStats publishes them: takedowns landed per 15 minutes, completion rate, submission attempts per 15 minutes, and the share of takedowns tried on them that they stuffed. Attempts per 15 is the one derived figure — landed ÷ completion rate — and it is omitted wherever either input is missing. UFCStats writes 0% where no attempt was recorded at all, so a percentage of exactly zero reads “n/a” here rather than as a measured rate. “Field” is the average fighter in that weight class, or across every division where a class is too small to average.
Pro record: 11-5. In the UFC: 3-4. Thomas Petersen’s last 7 UFC bouts, most recent first — the result in the cage, not our pick.
Straight off the official UFC fight record. Card names are left off on purpose: the only event labels in our data are derived, and we’d rather print nothing than print one that’s wrong.
