MANILA, Philippines -- Unbeaten American boxer Floyd Mayweather Jr. has announced that he approves of same-sex marriage, a day after rival Manny Pacquiao of the Philippines ignited a firestorm for saying he is against it.
Mayweather announced in his Twitter account that he supports United States President Barack Obama, who last week publicly announced his support for same-sex marriage.
At least one boxing website has criticized Mayweather for his tweet.
Scott Christ of Bad Left Hook noted that Mayweather "had a fit when it turned out that (Puerto Rican boxer) Miguel Cotto sleeps on the same bed as his buddy Bryan, and called his own father a 'f*ggot' on (HBO reality show) 24/7 in front of the world last year."
"A real progressive, that Floyd Mayweather," Christ added.
Mayweather made the announcement one day after Pacquiao, speaking with the National Conservative Examiner, said he disagreed with Obama's stance.
"God only expects man and woman to be together and to be legally married, only if they are so in love with each other," Pacquiao said.
The original Examiner report also quoted Leviticus 20:13, which says, "If a man has sexual relations with a man as one does with a woman, both of them have done what is detestable. They are to be put to death; their blood will be on their own heads."
Pacquiao has since clarified that he did not quote the Leviticus verse, and emphasized that is not against homosexuals.
"I'm not against gay people. I have a relative who is also gay," Pacquiao said in an interview with ABS-CBN's Dyan Castillejo. "We can't help it if they were born that way."
"What I'm critical of are actions that violate the word of God," he added.
The boxer said he never quoted Leviticus "because I haven't read the Book of Leviticus yet."
The author of the original report, Granville Ampong, eventually admitted that he was the one who cited the Bible verse, not Pacquiao.
But Pacquiao's opposition to same-sex marriage was widely criticized, especially in Los Angeles, where he is currently training for an upcoming bout against Timothy Bradley Jr.
Pacquiao was barred from LA hotspot The Grove, where he was supposed to make an appearance for the entertainment show "Extra."
Rick Jacobs, the founder and chairman of equality movement Courage Campaign, told LA Weekly that Pacquiao's comments will have an impact on his endorsements and sponsors in the United States.
