Fresh off what many consider to have been the sports event of the year, Floyd Mayweather Jr. vs. Conor McGregor, we’re hearing another colossal matchup may be in the works.

A highly-reliable source says a fight between Conor McGregor and Manny Pacquiao could be in the offing.

The fight would take place in Las Vegas, of course.

Further details aren’t known at this time, but a McGregor and Pacquiao fight seems entirely possible given the astronomical amounts of money generated by the Mayweather-McGregor spectacle, and the Mayweather-Pacquiao match before that.

When Mayweather fought Pacquiao in May 2015, the fight broke a variety of records, almost all of them related to money. The fight had more than 4.5 million pay-per-view purchases, and revenue generated from pay-per-view alone is believed to have been $400 million.

The purse alone for the Mayweather-McGregor fight, which Mayweather won, was $100 million for Floyd Mayweather, $30 million for Conor McGregor.

In the end, it’s believed Mayweather’s take was more than $300 million and McGregor snagged about $100 million.

Numbers like those are enough to bring just about any fighter back into the ring, even if they’re “retired.” Publicizing the fact a fight with McGregor would be the last of Pacqiao’s career would add another element of interest to a McGregor-Pacqiao matchup.

Of course, it’s not just the boxers who reap a windfall from these high-profile fights. They’re lucrative for everyone, and the biggest fights provide Las Vegas with a huge bump in room bookings, gambling and non-gambling revenue (like restaurants and nightclubs).

While we are not a sports person, we are a Las Vegas person, and mega-fights have an undeniable impact on the Las Vegas landscape, so we’ll be watching for what’s next in the world of guys punching each other in the face.

Update (12/9/17): Pacquiao mentions McGregor as possible opponent. Read more. We originally heard the fight could happen by the end of 2017, but it’s now looking like April 2018.
