Bernard Hopkins has the chance to beat his record for being the oldest fighter to win a world title against Tavoris Cloud this weekend.

Bernard Hopkins will try to make history again as he aims to break his own record for being the oldest fighter to win a major world title when he faces unbeaten Tavoris Cloud for a light heavyweight crown on Saturday.

The all-American showdown for Cloud's International Boxing Federation throne pits the 31-year-old champion, making his fifth title defence against Hopkins, 48.

"I'm not counting age. Everybody else is counting it," said Hopkins, who has won only one of his past four bouts.

"People know that I still can win a championship and beat most of these fighters out here and they are trying to use my age as something that is a death sentence. I've been hearing 'old' since I was 35."

Hopkins was 46 in 2011 when he beat Canada's Jean Pascal to win the World Boxing Council light-heavyweight crown, becoming the oldest fighter to win a major world title and surpassing heavyweight icon George Foreman's mark of 45.

Now 25 years after his first professional fight, Hopkins wants to make history again.

"It will mean a lot to me," he said. "I doubt very seriously that you will see a longevity in any sport of a Bernard Hopkins in a long time -- not in my lifetime.

"What drives me is that I'm not satisfied, even though I know I've done a lot. If I listened to most people, I would have never made history."

But even Hopkins, who has not fought since dropping a 12-round majority decision to Chad Dawson last April, knows Father Time is catching up to him.

"It must stop soon. It will. Everybody has to recognise that," Hopkins said. "Time is undefeated. No one can beat time."

Cloud, 24-0 with 19 knockouts, was confident of keeping his crown.

"Nobody can guarantee knockouts but I can guarantee a victory," Cloud said.
