WBC world heavyweight boxing champion Deontay Wilder was fighting fit at a pre-bout sparring session in a New York gym on Tuesday.

Wilder (40-1-0, 39KOs) was also full of words for his opponent Dominic Breazeale (20-0-1, 18KOs), repeating his claim that he is willing to kill in the ring.

"His life is on the line for this fight and I do mean his life," he told reporters.

After sparring and being stretched out, Wilder then showed his kinder side, welcoming his toddler inside the ring for a hug.

Saturday night's world title fight will see both boxers battle it out at the Brooklyn Center in New York.
