Joseph Parker earned less than $12.5million from his heavyweight unification title defeat to Anthony Joshua, according to promoter Eddie Hearn.
The Kiwi boxer lost his WBO title after a unanimous decision loss to Joshua in Cardiff on April 1.
Joshua's promoter Hearn took to Twitter to set the record straight after reports that Parker's earnings was at the $25m mark.
"Where an [sic] earth do you get that Parker purse from," Hearn said to a Twitter user who quoted Parker's reported earnings.
He added: "Cut in half and it's still too much."
