It’s a moment in sports history when Mike Tyson bit off a piece of Evander Holyfield’s ear in 1997. And the two boxers will discuss the incident together for the first time today on “The Oprah Winfrey Show.” On Monday, Tyson sat down with the media queen and shared the pain of losing his young daughter earlier in the year. He stated Holyfield’s head-butting provoked the biting incident, which disqualified him from the match. Tune in today for how the incident changed both their lives, and also hear of Michael Jackson’s last days from the “This Is It” documentary director.—CJ
