Gunnar Nelson: If Conor McGregor beats Floyd Mayweather, ‘I’m not sure that he will ever fight again’

One of the more talked about aspects of a potential crossover fight between UFC lightweight champion Conor McGregor and boxing’s Floyd Mayweather is what it would mean to the future. Namely, if McGregor cashes in on the type of payday that nears nine figures, in what form does he return to MMA?

His longtime training partner Gunnar Nelson was asked about that on a recent interview with Submission Radio. And Nelson is in the camp that believes McGregor may just ride off into the sunset.

Or, float off to do “something crazy.”

“You never know what he’s going to do next,” Nelson said.
