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. Each row is the fights that REACHED that round, so the share is the chance of it happening once the round has started — not a share of all fights. A fight that went three rounds is counted in all three rows, which is why these do not add up. 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.
