Murad Khalidov KO7 Sergey Kuzmin... Russian heavyweights Sergey Kuzmin and little-known Murad Khalidov staged a rockem-sockem-robots fight on an IBA pro show in Saint Petersburg, Russia. Khalidov scored the upset with a brutal seventh-round knockout. The winner is listed as 11-0 with no traditional boxing fights since 2014, but he has stayed active in bare knuckle and Russian "cage boxing" fights that are difficult to verify. The win over Kuzmin puts Khalidov in good company. Now 20-3 including the World Series of Boxing, Kuzmin's prior losses were to Michael Hunter, Martin Bakole and Filip Hrgovic (World Series of Boxing) and those were all by decision.
