Across the ten bouts that produced a result, four ended by knockout, two by submission and four on the judges' scorecards — six stoppages in ten fights. Every decision was unanimous: not one result divided the judges.
The quickest finish belonged to James Te Huna, who stopped Ricardo Romero after 47 seconds, and four of the six finishes came inside the opening round. The longest was Jon Jones's submission of Quinton Jackson, 16 minutes and 14 seconds in. End to end, the ten fights filled one hour and 41 minutes of cage time.
The main card finished at the higher rate: three of five, against three of the five below it. Tony Ferguson (knockout, round one), Takeya Mizugaki (knockout, round two) and James Te Huna (knockout, round one) all closed before the judges were needed.
