You might be wondering when the fight between Conor McGregor and Floyd Mayweather actually starts.
It's a bit tricky. The undercard begins at 9 p.m. ET on Saturday, but there's no exact start time for Mayweather and McGregor.
We do know that the two fighters are supposed to enter the ring around 11 p.m. ET. According to The Los Angeles Times, the fight will start at 11:55 p.m. ET. Whether that actually holds up remains to be seen.
The much-hyped fight will finally take place on Saturday night at T-Mobile Arena in Las Vegas. Mayweather is a big favorite, but expect fireworks either way.
