What counts. A knockout here is any bout the official record ends by KO/TKO, including a doctor’s stoppage, which UFCStats files as its own method. A fight is a UFC bout on the official record with a result. Draws, no-contests and overturned results are excluded from every count on this page; disqualifications and could-not-continues are counted as fights, which is why the knockout, submission and decision shares do not add up to 100%. How this table is cut. Divisions as the official record labels the bout, heaviest table first by number of fights. 1 division withheld. Women's Featherweight rest on fewer than 30 fights (29 between them), so no percentage is printed for it — a rate off a handful of bouts is arithmetic, not a statistic. 259 fights are outside this table. They carry no division on the record at all — catchweight, open weight and the 1990s tournament bouts. They are not missing from our record — they are on the year-by-year archive like every other bout; there is simply no row here for them to sit in. Check us. Every number here is recomputed from the official UFC statistical record on each build — nothing on this page is typed in by hand. Search every fight to filter the same record yourself, or start from the year-by-year archive.
