If talks between Conor McGregor and Floyd Mayweather Jr. break down at some point, the Ultimate Fighting Championship (UFC) does not have to worry about it because a lot of mixed martial arts (MMA) fighters are currently waiting in line to fight the UFC lightweight champion. Furthermore, Mayweather isn't the only boxer who wants a piece of McGregor either. Ricardo Mayorga has already expressed his willingness to fight the Irishman, and now pound-for-pound boxing great Manny Pacquiao has also added his name to the list.

In an interview with FOX Sports, Pacquiao revealed that he's willing to step into the ring with McGregor if Mayweather refuses to take the fight. He also clarified that it has to be a boxing match, not an MMA bout. "In boxing? In boxing (I would) but not in (UFC), just boxing," he stated.

In an interview with Yahoo Sports' Kevin Iole, Pacquiao's promoter, Bob Arum, revealed that Top Rank president Todd duBoef was going to call UFC chief operating officer Lawrence Epstein to talk about a possible match between the two.

"Todd has agreed to call Lawrence, and they have a great relationship, and tell him what Manny's interest is and see what happens. That's it," he said.

But before a fight can be made, Arum has to deal with UFC president Dana White as well. Unfortunately, White doesn't want to do business with Arum.

"Listen, I love Manny Pacquiao. But I don't love Bob Arum. You can tell Arum to save his money and not make any calls over here because we aren't doing business with him," he said.

There goes the potential fight between the two. That bout would have been as intriguing as the match between McGregor and Mayweather.

Right now, the UFC and Mayweather's camp are still working on the terms of the fight. A fight between the two is still uncertain, but it's getting closer to reality than ever before.
