Now that Calzaghe is fighting at light heavy, you can add Evander Holyfield, Michael Spinks, Dwight Muhammed Qawi, Eddie Mustafa Muhammed, Matthew Saad Muhammed

Those ones for sure.

If you include probablies, you can add Yaqui Lopez, John Conteh, Marvin Johnson, Victor Galindez, James Scott.

I'm sure there are others.
