World champion in junior middleweight according to WBO Tim Tszyu reported that his grandfather forbade him to spar with his brother Nikita, who is also a professional boxer.
“It (ban - note) has been lifted. For one week. Then grandfather again forbade us to spar. This was when I was preparing for the previous fight. I spent 6 rounds with someone, and then Nikita went out for the remaining 4 rounds. I was tired, broken, and Nikita came out all so fresh and knocked all the spirit out of me. Head, body, head, body. I left the ring red-faced, thinking about life. No, the ban came after our next sparring. Because I made Nikita my first sparring partner. And I gave him a cradle. A little bit. After that, grandfather said: “That’s enough.”
