Mike Tyson may be one of the greatest boxers to ever get in the ring, but the heavyweight champion has become dedicated to a more elegant sport. Tennis has become a major part of Tyson's life, with the 55-year-old going so far as to say the sport "changed [his] life."
At the US Open and Indian Wells, Tyson can be frequently seen cheering on his favorite players. Reportedly, the boxer is a huge Novak Djokovic and Serena Williams fan, even teaching the former world No. 1 how to box. Tyson posted on Twitter a video of him holding the punching bag for Williams.
