By Allan Fox: If Floyd Mayweather Jr. wants to fight in September this year, he’s going to need to find another opponent rather than trying to fight Conor McGregor. The reason for that is McGregor is now scheduled to fight Nate Diaz in a rematch in UFC 202 on August 20 in Las Vegas, Nevada.
McGregor won’t be able to fight Diaz in August and then turn around and face Mayweather in September. That doesn’t mean that McGregor can’t fight Mayweather this year, because it’s possible that the fight can always take place in December if Mayweather wants the fight bad enough.
