Manny Pacquiao will earn a guaranteed $20 million (£13.7m, €18.4m) in his final bout against Timothy Bradley in April − $140m less than the purse he reportedly took home after last year's showdown with Floyd Mayweather Jnr. Pacquiao, 37, will enter the ring for the final time at the MGM Grand on 9 April for a third meeting with Bradley, a decider with both men each having claimed a win in their previous battles.

The Filipino returns having not fought since his unanimous decision loss to Mayweather in May 2015, a fight that went down as the richest in the history of the sport.

Pacquiao took the smaller share of a 40-60 split of purse on that occasion, a reported $160m. But the final fight of his glittering career will see him take home a comparatively modest sum.

"I don't know about Bradley, but I can confirm Pacquiao is getting a $20m fight purse," Pacquiao's promoter Bob Arum was quoted as saying by ABS.

Pacquiao underwent shoulder surgery in the aftermath of his defeat to Pacquiao, only the sixth loss of his 21-year career. His fourth career defeat came at the hands of Bradley when he lost his WBO welterweight title after a controversial split decision, one that sparked widespread criticism in 2012.

The Filipino would get his revenge two years later, however, regaining his title from the 32-year-old via a unanimous decision in Las Vegas.
