On Saturday night at Treasure Island Hotel & Casino in Las Vegas, legendary former undisputed heavyweight champion Mike Tyson was reunited with announcer Jim Gray, who won an Emmy for his interview with Tyson following the infamous ear-bite fight with Evander Holyfield on June 28, 1997. “I’ve been working on myself,’’ Tyson told Gray on Showtime. “I’m in the mood of being truly grateful of my life. I realize I have nothing to be mad at. I never dreamed I’d be living at this time (but) I’ve gotten as much as I gave. I’ve been blessed in my life. I just want to contribute to humanity now.” In response to Gray asking about George Foreman winning a title at age 45 and if Tyson, at 43, would contemplate a comeback, Tyson said: “If this guy (referring to Don King) is going to pay for my training -- my training team costs a lot of money -- anything is possible. I don’t see it happening but anything is possible.’’
