Floyd Mayweather, who co-promoted Saturday’s card with DiBella Entertainment, left open the door for a possible fight with UFC champion Conor McGregor.

“I’m a businessman when it’s all said and done,” Mayweather said before Saturday night’s super middleweight title fight between Badou Jack and James DeGale. “It’s all about entertainment and we can do some crazy numbers if that fight happens. If it’s Conor McGregor it makes sense to me. No one else makes sense to me.”

Showtime executive Stephen Espinoza said he thinks a Mayweather-McGregor bout could do box-office business similar to Mayweather’s record-breaking fight with Manny Pacquiao. Mayweather-Pacquiao generated a record 4.4 million pay-per-view buys and nearly $500 million in revenue when the two boxers met on May 2, 2015.

“It’s tough for me to think whoever bought Mayweather-Pacquiao wouldn’t buy Mayweather-McGregor,” Espinoza said. “As soon as Mayweather-Pacquiao was over, we said we’d never see that kind of volume again. Maybe we would with a fight like Mayweather-McGregor.”
