Mihajlovic, 25, is ranked fifth in the International Boxing Federation and last fought in April. Radovan, who previously held the IBF European belt, returned to the ring in March after a nearly year-long hiatus.
The title of IBF world champion in the category up to 72.5 kg is currently vacant. Previously, it belonged to Gennady Golovkin, and on July 1, Esquiva Falco (30-0, 20 KOs) and Vincenzo Gualtieri (20-0-1, 7 KOs) will fight for it.
