These two cards shouldn't impact UFC 223, 224, 225's viewership during the prelims, but there is a chance fans of both sports could bolt when Wilder and Ortiz climb into the ring sometime around 10:15 pm ET. The Kovalev-Mikhalkin bout could be less of an issue because it starts later, though the co-feature Dmitry Bivol and Sullivan Barrera is an interesting one for hardcore boxing fans. Combat sports are the most obvious potential conflict, but UFC 223, 224, 225's biggest competition will likely come from basketball. Not only are the Boston Celtics taking on the Houston Rockets in a high-profile regular-season matchup at 8:30 pm ET on ABC, North Carolina vs. Duke (8:15-10:15) and UCLA vs. USC (10:15-12:15) on ESPN runs straight through the FS1 prelims and PPV main card.
