The two will clash at Afro Motel in MalawiÃ¢â‚¬â„¢s commercial city, Blantyre in a non-title bout organised by PMJ Boxing Promotions.
PMJ managing director Gerald Lipikwe said they decided to do a public weigh-in to add pomp to the fight.
Ã¢â‚¬Å“The weigh-in will be held at the venue of the bout and we will have a media day where the two boxers will give final interviews.
Ã¢â‚¬Å“They will fight at 60 kilogrammes. Kayuni was weighing 62 kilogrammes whereas Masamba was at 58.5 kilogrammes,Ã¢â‚¬Â said Lipikwe. He added that the bout has attracted a number of sponsors whom he said will be revealed as the boxers have a weigh-in.
Masamba was camping in Lilongwe for the past week and was expected in Blantyre last night.
Ã¢â‚¬Å“I have managed to increase my weight to 59.8kg. I should be 60kg by Friday,Ã¢â‚¬Â said Masamba on Wednesday.
Kayuni could not be reached for comment.
Whereas pride may be at stake for Masamba, having lost twice to MalaniÃ¢â‚¬â„¢s elder brother Osgood, last year, the bout attracts an appetising K170 000 ($1 017) prize for the winner.
