A breathtaking video for "Mike Iron" ... Tyson: I'm back

Former world champion Mike Tyson continued to excite boxing fans around the world with the possibility of returning to the tracks again, when he posted on his Instagram account another video during the training that he ended by saying, "I am back."

Tyson, 53, caught the attention of the boxing world last week when he released a video during training, during which he demonstrated the strength and speed of his penis that enabled him to be the first to collect World Boxing Council titles, the International Boxing Association and the World Boxing Association.

Tyson said he is considering returning to boxing in exhibition matches to raise money for charity.

In his latest video, Tyson appeared during heavy training and punched, in another show of his power that made him have one of the most punched fears competitors.

Since he mentioned the possibility of his return, some boxers have tried to get an opportunity to face "Mike Iron."

To confront Tyson, the former New Zealander Sony Bill Williams, the former rugby player who switched to boxing and won seven games, was nominated by a knockout, and Australian Paul Gallen, another rugby player, won nine clashes and lost once.

But the closest possibility is Evander Holyfield, who has already faced Tyson in a set of the most epic matches of their professional careers.

If Tyson - who retired in 2005 after losing to Kevin McBride - returned to boxing, he would follow the steps of Floyd Mayweather and Manny Pacquiao, who returned from retirement to participate in exhibition matches.

Tyson - who became the youngest heavyweight world champion when he defeated Trevor Berbick in 1986 at the age of 20 - won 50 of the 58 tournaments in his career before retiring.
