Krzysztof Jotko beat Kerim Engizek by unanimous decision after five rounds in the main event of OKTAGON 91 at the Lanxess Arena in Cologne. In the co-main event, Mochamed Machaev beat Gjoni Palokaj by knockout at 2:36 of round one at featherweight.
Across the nine bouts that produced a result, three ended by knockout, two by submission and four on the judges' scorecards — five stoppages in nine fights. Every decision was unanimous: not one result divided the judges.
The quickest finish belonged to Mochamed Machaev, who stopped Gjoni Palokaj at 2:36 of round one, and three of the five finishes came inside the opening round. The longest was Cihad Akipa's knockout of Máté Kertész, 12 minutes and 6 seconds in. End to end, the nine fights filled one hour and 40 minutes of cage time.
The main card finished at the higher rate: three of four, against two of the five below it. Iwan Tagner (submission, round one) and Nicolaj Wagner (knockout, round one) all closed before the judges were needed.
Six weight classes were used, middleweight most often with three bouts.
