Danny Williams, a former opponent of undisputed heavyweight champion Mike Tyson, believes his former foe will do some real damage on Roy Jones Jr.

Tyson, 54-years-old, will face Jones, a four division champion, in an eight round exhibition fight on November 28 in Los Angeles. The fight will be carried on pay-per-view.

Williams shocked the world when he stopped Tyson in four rounds in 2004. Tyson would retire from boxing the following year after suffering a stoppage loss to journeyman Kevin McBride.

When discussing Tyson's fight with Jones, Williams issued a warning.

"I think Roy is going to get seriously hurt. He is a natural middleweight," Williams told The Sun.

Williams, 47-years-old, recently announced his own retirement from boxing amid health concerns.

Over the weekend in Russia, Williams suffered the 29th loss of his career at the hands of Sergei Kharitonov, who was making his pro debut.

The fight was stopped in the second round, as Williams' opponent appeared to be pleading with the referee to stop the contest.

Unfortunately, it's not the first time that Williams promised to retire from boxing.

The high point in Williams' career was the knockout of Tyson - which led to a crack at then WBC heavyweight champion Vitali Klitschko, who won the bout with ease.

Williams would also secure an upset decision win over Olympic gold medal winner Audley Harrison in 2005, but lost the rematch.

Earlier in the year, Williams rolled the dice for a big pay day by placing his name in the hat to become the comeback opponent for Mike Tyson.

"It’s definitely a fight I want. I’m very interested in facing Mike Tyson again," Williams had stated.
