Mike Tyson is 54 years old but still thinks he would have no trouble handling Conor McGregor in a boxing match.

In fact, Iron Mike said he would "kick his ass" when talking about McGregor on The Tonight Show Starring Jimmy Fallon (55 seconds into the video):

On the one hand, McGregor is an MMA fighter and Tyson is one of the most legendary boxers in the sport's history. However, McGregor is 22 years younger than Tyson and held his own against Floyd Mayweather Jr. in a 2017 boxing match.

Mayweather improved to 50-0 in his career with the win over McGregor, but the latter lasted into the 10th round before losing via technical knockout.

Tyson is 50-6-0 with 44 knockouts but hasn't fought since 2005. He also said training is "really painful" at his age:

For now, it's probably better for the former world heavyweight champion to focus on his comeback bout against Roy Jones Jr. than trying his hand against McGregor in a fight.
