If you were wondering how much of a statistical anomaly it was that UFC 91 only had one judge’s decision, Sherdog’s got you covered:
Only one match at UFC 91 — the lightweight bout between Gurgel and Riley — went to the judges. That was the lowest total for a numbered UFC show since UFC 66 in December 2006. That event, which featured the Chuck Liddell-Tito Ortiz rematch, also saw only one fight go the distance. In fact, only eight of the last 50 numbered UFC shows — 91, 66, 60, 55, 53, 50, 49 and 47 — have produced fewer than two decisions.
