Unified light heavyweight titleholder Sergey Kovalev, who lived up to his "Krusher" nickname with his one-sided third-round knockout of mandatory challenger Nadjib Mohammedi on Saturday night at the Mandalay Bay Events Center in Las Vegas, averaged 1.014 million viewers for the live airing on HBO, according to Nielsen Media Research.
The fight, Kovalev's seventh on HBO, peaked at 1.082 million viewers.
The average audience was only slightly less than Kovalev's eighth-round knockout of former champion Jean Pascal in March, which averaged 1.152,000 viewers.
The opening bout on Saturday's card, Pascal's controversial decision against Yunieski Gonzalez, averaged 883,000 viewers. The 10-round fight of the year candidate peaked at 1.028 million viewers.
The HBO telecast was on opposite a Premier Boxing Champions show, also in Las Vegas at The Palms, on NBC Sports Net. That card, headlined by Beibut Shumenov's decision win against B.J. Flores to claim a vacant interim cruiserweight belt, averaged just 241,000 viewers, peaking at 422,000, on a network available in nearly three times as many homes as HBO, although one without the storied boxing history of HBO.
