LAS VEGAS – Bob Arum was at a party on Super Bowl Sunday, surrounded by about 80 people.

When the first of two commercials promoting the Deontay Wilder-Tyson Fury rematch aired during the Chiefs-49ers game, partygoers began looking at Arum. No one had ever seen a boxing commercial during the most-watched annual sporting event in the United States.

“They were like, ‘Hey, you’ve got a real sport! This is major league,’ ” Arum recalled. “And it’s true. The message out there now is boxing is back and it’s a major-league sport.”
