UFC champion Conor McGregor is hoping to do the unthinkable tomorrow night (Sat., Aug. 26, 2017) when he takes on undefeated boxer Floyd Mayweather Jr. live on Showtime pay-per-view (PPV) from inside T-Mobile Arena in Las Vegas, Nevada. If McGregor is able to punch his way past Mayweather he’ll prove nearly the entire boxing community wrong and change the landscape of combat sports forever.
