Manny Pacquiao has agreed to give Floyd Mayweather the bigger part of a 55-45 financial split if they should fight, putting the pressure on Mayweather to agree to the much anticipated fight, Yahoo! Sports reported Thursday.
Pacquiao made the announcements of his agreement to take just 45 percent during appearances on two ESPN television programs.
A match between Pacquiao and Mayweather could be the most lucrative bout in boxing history.
Pacquiao is scheduled to meets Juan Manuel Marquez for a fourth time in his next bout on Dec. 8 in Las Vegas. Mayweather has not fought since he won a unanimous decision over Miguel Cotto on May 5. Mayweather has not schedule his next fight.
An agreement to take 45 percent is a departure for Pacquiao, who has said for the past 18 months he would not agree to a fight with Mayweather unless there was a 50-50 financial split.
The other major barrier to arranging the fight was believed to be Mayweather's demand for Olympic-style drug testing. Pacquiao has changed his stance on that too, saying he would comply with the tests.
In a telephone interview with Yahoo! Sports on Monday, Pacquiao made no mention of a purse split, but he was optimistic about the possibility of a fight with Mayweather.
"I think Mayweather will be next," Pacquiao said, although he did not say why.
Mayweather must also stay out of further legal trouble. He was paroled in August after serving nearly two months of a six-month sentence for misdemeanor domestic violence.
The Las Vegas Review-Journal reported on Tuesday that Melissa Brim had called 911 following an alleged verbal altercation with Mayweather on Sept. 9. However, police told the Review-Journal it found no signs of physical violence. Brim is the mother of one of Mayweather's children.
