Evander Holyfield will return to the ring at age 57.

Last night, the only undisputed champion ever in two weigh classes announced he is training to fight for charity.

This comes days after his rival Mike Tyson, 53, said he was ready for a comeback.

Tyson and Holyfield fought twice in the mid-90s.  The first fight ended in a surprise knockout by Holyfield.  In the second, Tyson notoriously resorted to cannibalism and was disqualified.

Would you like to see them square up again?
