Tonight"s schedule Good evening and welcome to tonight’s quinquagenarian showdown between Mike Tyson and Roy Jones Jr. Two of the most famous prizefighters of their generation are returning to the squared circle for a scheduled eight-round heavyweight exhibition at the Staples Center in Los Angeles. While the bout has been sanctioned by the California State Athletic Commission, it’s officially an exhibition and the result will appear on neither man’s professional record. Tyson, 54, held the undisputed heavyweight champion from 1987 through 1990. Jones, 51, won titles in four different weight classes and was considered the best pound-for-pound boxer of his time. A number of precautions have been taken to protect the fighters’ health. The rounds will be shorter than usual – two minutes instead of the standard three – and both men will be wearing larger-than-usual 12oz gloves. The televised pay-per-view card is about to start with three preliminary bouts ahehqad of the main event between Tyson and Jones, who will likely make their ringwalks around 11.30pm ET (4.30am GMT).
