I can't remember which UFC it was but the main event was "The Russian Bear" Oleg Taktarov vs. Tank Abbott, in Denver, Colorado. This was before time limits and rounds. Remember it's in Denver, the air is thinner and the match was more than a hour long with nothing going on. They were both on the ground, Tank on top of Oleg and both were tired and exhausted. Most boring fight ever and Big John restarted them on their feet like 4 or 5 times and would end up with Tank on top. After an hour Tank finally messes up and taps out to Oleg. Neither one of them got up after the fight was over, they were too exhausted and both needed oxygen. More than an hour of nothing.
