Oleksandr Usyk may be one of the toughest sportsmen on the planet, but that's nothing compared to the Ukrainian's mother.
Usyk is set to finally face Tyson Fury one-on-one this weekend when the two heavyweights clash in one of the most anticipated fights of recent memory.
The original fight in February was postponed due to Fury's eye injury, but ahead of the clash in Saudi Arabia, Usyk spoke to Boxing King Media about the shoving match that occurred at the original press conference last November.
Asked about his mother's reaction to the altercation, Usyk revealed she was far from happy about what she saw and warned the Brit boxer.
He said: "My mom was angry, [she asked] ‘why did this man push you?’ I said, 'Mum, it’s just show please relax’. [She said], ‘listen, say [to him], if this man pushes you, I kill [him].'”
