The day of reckoning is just four days away for old-school boxer Floyd “Money” Mayweather Jr. and mixed-martial arts specialist Conor McGregor. There are lots of at stake in Saturday night’s mega-bout.

Many say the outcome of Saturday’s match will probably determine the relevance of boxing. Once upon a time, boxing is a huge sporting event. Matches of boxing legends Muhammad Ali, George Foreman, Sugar Ray Leonard, and Mike Tyson drew in thousands of crowds and filled hundreds of arenas worldwide.

But the interest of people in boxing waned dramatically due to controversial outcomes and allegations of match-fixing. It didn’t help that these happened at a period when mixed-martial arts was emerging from its obscurity. People got fed up with boxing and turned to mixed-martial arts.

Mixed martial-arts, on the other, hand is fighting for recognition. Yes, the popularity of mixed-martial arts has grown exponentially over the years but it remains to be a small fry compared to boxing. A McGregor win on Saturday will put it on the same league as boxing.
