UFC 46: Supernatural took place at the Mandalay Bay Events Center in Las Vegas on 31 January 2004. Vitor Belfort won the light heavyweight championship from Randy Couture, and B.J. Penn took the welterweight title from Matt Hughes. Those two first-round results explain the headline, but they account for only part of an eight-bout event.
All eight UFC 46 results
The winner appears first. KO/TKO is a broad category; a more specific explanation is included only where the source supports it. Round and time identify the finish within its final round.

Round/time fields are listed in the UFC event record. UFC's 2020 event retrospective identifies all eight winners; the linked UFCStats entries corroborate the specified bouts. The event page's inconsistent win/loss labels should not override the named outcomes in those records.
Two title changes, two different endings
Belfort's result is recorded as a doctor's-stoppage TKO. The UFC's 2011 Belfort retrospective attributes the cut to a seam on his glove after a grazing straight left. That is a dated promoter account, not a medical assessment by this site. The result can be reported precisely without turning the short elapsed time into a claim that Couture was knocked unconscious.
Penn's outcome is a submission, and the Hughes statistics record specifies a rear-naked choke at 4:39. UFC's account of Penn's career describes his move from lightweight competition to the welterweight title challenge. It also records Hughes entering with five consecutive title defences. Five successful defences is different from describing the Penn loss as a sixth successful defence.
The two title bouts total 0:49 + 4:39 = 5:28 of fighting. That calculation measures duration, not how impressive the performances were. It also should not be described as the time taken to complete the event: the other six bouts still need to be counted.
One decision detail remains disputed between UFC sources
Both UFC sources support Thomson's decision win over França. The event page labels it a majority decision; the 20 April 2020 retrospective calls it unanimous and reports three 29–28 cards. Those descriptions disagree.
The table therefore retains the shared, supported fact—a Thomson decision win—and leaves the subtype open. If you are compiling results, store the outcome separately from the decision type and keep the source date beside each claim. Resolving this detail would require the original official score record; copying the more precise-looking label does not resolve the conflict.
A title-only recap misses most of the fighting time
The card contains four finishes and four decision wins. Its three first-round finishes were followed, in duration terms, by Mir's second-round stoppage: 5:00 + 4:21 = 9:21. The four three-round decisions each account for 15 minutes of fighting, or 60 minutes combined. These are calculations from the result clocks, excluding breaks and broadcast material.
That is why a short championship recap cannot stand in for a full event guide. A reader comparing finishes needs the final round and clock; a reader comparing the whole card needs every bout. Neither set of numbers tells us which contest was best.
One of those decisions was also St-Pierre's UFC debut. Keep that milestone separate from later achievements: this page records what happened at UFC 46 rather than assigning the newcomer a reputation built by subsequent fights.
Revision and sources
Revised 13 September 2026: this complete replacement rebuilds the eight-bout results, attributes the stoppage explanation and exposes the conflicting decision descriptions. Unnecessary private-life allegations and unsupported bonus, attendance and weight-miss assertions from the old article have been removed; their omission is not a finding that they were false.
Prepared with AI assistance and checked against the linked primary source text on 13 September 2026. Retrospectives are identified as later accounts. No attendance, interview by this site, independent medical or criminal-record investigation, or complete fight-footage review is claimed.
