Does Floyd Mayweather really want to fight MMA? His enthusiasm on the topic seems to depend on when you ask him.

In late March, Mayweather called it a “50-50 chance” that he’d fight in the UFC by the end of the year. But now?

“I’m not worried about the octagon or the boxing ring,” Mayweather said Tuesday, according to Filipino media outlet ABS-CBN News.

Mayweather (50-0 boxing) had said before that he’d already started training for a possible MMA fight. But he’s been traveling the world of late, with the Philippines being his latest stop on a trip that’s included Dubai, Singapore, Bali, and Bangkok.

That might explain the change in tune.

“As of right now, I’m touring around the world, doing different things, embracing my fans, getting love from all around the world,” Mayweather said. “Right now I’m just traveling. I don’t know what the future holds, but as of right now, I’m retired.”

He continued, “I’m not thinking about fighting right now.”

Be that as it may, a person close to Mayweather believes he shouldn’t be doubted.

During a recent appearance on MMAjunkie Radio, Greg La Rosa, Mayweather’s head of security, explained why the undefeated boxing champion should be taken seriously when it comes to a possible fight in the UFC.

“I think he might do it. I think he might come back,” La Rosa said. “Never know. I don’t know who it would be against, because that stuff would be all behind the scenes, a little out of my reach. But I think he might do it. …

“A lot of people are calling bullshit on this one, but we’ll just have to see. He’s around camp, he’s talking about it, and he’s not kidding when he talks to Jim Gray there and says if I come back it’ll be for MMA. That’s not a joke that he’s making.”

Mayweather previously said he would train with UFC welterweight champion Tyron Woodley to help shore up his all-around fight game, and La Rosa confirmed to MMAjunkie Radio that he’s seen Woodley around.

Mayweather retired (again) after defeating Conor McGregor by 10th-round TKO in a boxing match last summer that did massive numbers at the box office. A Mayweather venture into the octagon would also figure to do big business. McGregor naturally has been discussed as a possible opponent.

La Rosa couldn’t say for sure who Mayweather would want to fight. He just knows it’s something “Money” is seriously considering.

“Man, if I had to guess, I’d say it’s closer to happening,” La Rosa said.
