Hardest to knock out in the UFC

What it measures. KO/TKO losses as % of decided fights. Lower is better. Formula. KO and TKO losses divided by decided fights. Lower is better. Doctor's stoppages are not counted as knockouts. Minimum sample. Career: at least 8 fights and 8 qualifying fights. Last five: at least 4 fights and 4 qualifying fights. The Sample column is the amount behind each figure (qualifying fights). A fighter below the minimum is not ranked and does not appear here; the figure is still shown, greyed, on their own page. Order. The table follows the published rank, which for rate stats is computed from a confidence-adjusted score rather than the raw figure, so the values can sit slightly out of order. The value shown is always the raw figure. Last bout and Active. The date of the fighter's most recent fight in this data. Active means a bout in the last 18 months. Coverage. Every figure is built from UFC fights that have round-by-round data. Some older bouts do not, and are left out rather than estimated. Check us.
