Sunday’s Pro FC 57 event ended in dramatic fashion – with the headliner and also its aftermath. The show, which took place at Sports Palace in the Russian city of Rostov-on-Don, featured a middleweight main event between Shamil Abdulkhalikov  and Mikhail Kolobegov . After three rounds, rather than awarding Abdulkhalikov (10-4) what appeared to be a clearcut decision victory, officials reportedly cited a “ judicial error ” and added a fourth round. With the second chance, Kolobegov (9-3) then laded a flying-knee knockout. And then all hell broke loose.
