The ratings for the UFC 210 prelims on FS1, prior to the Daniel Cormier vs. Anthony "Rumble" Johnson pay-per-view card, did 723,000 viewers, the lowest of the three such events so far this year.
The viewership was also lower than all but one of the pay-per-view prelims of 2016. The only show last year that did a lower number was the prelims before UFC 204, the Michael Bisping vs. Dan Henderson middleweight title fight. That show did 678,000 viewers going against a number of college football games as well as the Major League Baseball playoffs.
