Britain's Dereck Chisora will be fined for slapping heavyweight champion Vitali Klitschko during the weigh-in for Saturday's title fight in Munich.
The World Boxing Council [WBC] condemned Chisora and stated a hearing would be held to determine the fine.
WBC president Jose Sulaiman said: "The organisation has decided to fine Chisora for not complying with the fair play that is required in all sports.
"Boxing, even though it is violent, is a sport of gentlemen and fair play."
Sulaiman added on the organisation's website that Klitschko had behaved like a professional despite the provocation at Friday's weigh-in.
Ukrainian WBC champion Klitschko, 40, said the fight will be among his last.
His brother, Wladimir, holds the WBA, IBF, WBO and IBO titles.
Klitschko said on Friday: "He hit me not like a boxer but like a woman, with an open hand.
"If he wants to fight properly, he must do that with his fists. I'll be hitting him back tomorrow, in the ring."
Chisora, 28, is a big underdog going into the fight after suffering two high-profile losses in his last three fights.
Chisora weighed in at 17st 3lbs, just a pound heavier than his lightest weight for a professional bout. Klitschko came in at 17st 6lbs.
