LAS VEGAS – There seemed to be good vibes at the UFC on ESPN 60 official weigh-ins after everyone hit their marks. But then things took a turn into #ApexVibes territory when the co-main event, just minutes after it had become official when both fighters made weight, was scrapped. Junyong Park (17-6 MMA, 7-3 UFC) made weight without issues for his middleweight co-main event against Brad Tavares (20-9 MMA, 15-9 UFC) about 10 minutes into the two-hour window. After that, he had to go through customary physical checks with the Nevada Athletic Commission, and he didn’t pass. Tavares made weight a bit later at 185.5, but it proved to be pointless when the commission ruled Park out at UFC on ESPN 60 (ESPN/ESPN+), which takes place Saturday at the UFC Apex in Las Vegas. That makes the featherweight fight between Seungwoo Choi (11-6 MMA, 4-5 UFC) and Steve Garcia (15-5 MMA, 4-2 UFC) the new co-main event.
