Bernard Hopkins recently said he is interested in facing Floyd Mayweather, Jr., and the reigning pound-for-pound king sounded like he is open to the possibility.

Mayweather told BoxingScene on Wednesday he was not surprised with Hopkins' challenge, saying that the 49-year-old champion was just doing what he is supposed to do.

When asked about the possibility of facing Hopkins, Mayweather said that anything is possible, but he pointed out that he will not think about it yet, saying that he is focused on his upcoming fight.

Mayweather, who is still undefeated in 45 professional fights, will go up against Marcos Maidana on May 3 at the MGM Grand in Las Vegas, and the reigning WBC welterweight champion said that he is expecting a tough fight.

"He's supposed to [call me out]. It's part of the game. He's supposed to," Mayweather said. "We don't know what the future holds for Floyd Mayweather. Anything is possible. But as of right now Maidana is a guy that I can't overlook. Maidana has an 80 percent knockout ratio, and I know this guy is going to come and try to destroy me."

Hopkins opened up the idea of facing Mayweather after winning against Beibut Shumenov in their International Boxing Federation and World Boxing Association light heavyweight title showdown on Saturday.

"I'll give anybody a run for their money," Hopkins said. "If they are unbeaten, I will take their 0, give them their first loss. I could make 165, 168 (pounds) real comfortably. If I do a fight, it would be one of the biggest in the world. We will do it in a stadium somewhere."

Hopkins said that the fight could be called "50-50" since he will be 50 years old by that time, while Mayweather is chasing 50 wins to surpass Rocky Marciano's 49-0 record.

"After I become the undisputed light-heavyweight champion of the world, if there was one big fight out there, I know what I would call it: 50-50. He wants to pass Marciano. He wants to get to 50, and I am 50. That would be huge. I would love to do that," Hopkins said.

It is still unknown, though, whether or not the Mayweather vs Hopkins showdown will take place, considering the huge weight difference. Hopkins said that he could make 165 or 168 pounds easily, but Mayweather usually walks around 150 punds between fights.
