How the card was decided
Across the nine bouts that produced a result, four ended by knockout, two by submission and three on the judges' scorecards — six stoppages in nine fights. Every decision was unanimous: not one result divided the judges.
Finishes and fight times
The quickest finish belonged to Mariusz Joniak, who stopped Tobiasz Le at 1:10 of round one, and three of the six finishes came inside the opening round. The longest was Valeriu Mircea's submission of Leo Brichta, 17 minutes and 45 seconds in. End to end, the nine fights filled one hour and 27 minutes of cage time.
Main card against the prelims
The preliminary card out-finished the main card: two of its two results came early, against four of the seven above it. Mariusz Joniak (knockout, round one) and Wiktoria Czyżewska (knockout, round one) all closed before the judges were needed.
Countries, weight classes and broadcast
Eight weight classes were used, welterweight most often with two bouts. KSWTV carried all nine bouts, split across a main card and one preliminary block.
