The UFC has run 11 pay-per-view events so far in 2017. In seven of them, a fighter either dropped out in the day or days leading into the event (almost always due to a tough weight cut) or there was some kind of collective holding of breath during official weigh-ins.
In 38 UFC events thus far, 36 times there was either a fighter missing weight or falling out of the fight in the days before due to circumstances compounded by weight cutting. And UFC 219 on Dec. 30 features two fighters — Cris Cyborg and Khabib Nurmagomedov — in the main and co-main event, respectively, who are known for having a tough time making weight.
