Garner won the vacant European title in front of a packed crowd at the Bournemouth International Centre in March.
He outclassed Spain’s Salvador Jimenez on points to put himself into the mix for some big fights in the 130lbs division.
Garner is undefeated in 17 contests and will face Bellotti, 34, who, despite having five losses to his name, has won his past six fights, with his last an impressive win over Michael Gomez Jr.
Edmondson defended his Commonwealth title in March when he outpointed the previously unbeaten Oluwatosin Kejawa in Bournemouth.
He won his titles in late 2024 when he beat Dan Azeez in London, but now the BBBC have ordered him to defend them against an opponent who has won all 12 of his fights, including eight knockouts, since his professional debut in 2020.
Edmondson, known as ‘The Saint’, and Nottingham’s Taylor, 30, have clashed at their past two respective bouts, willing each other to come through scheduled fights to set up what promises to be a fiery affair.
