A trend started by Lennox Lewis and Hasim Rahman last year apparently still has some life in it.

Those two men were separated by glass and security guards in the build-up to their rematch in Las Vegas last November and the same provisions are in operation for the fight between Oscar de la Hoya and Fernando Vargas.

In both cases, the decision was based on the animosity, mutual hatred and previous actions of both fighters.

"It was my decision and we're not even going to have the traditional posing," said Marc Ratner, the Nevada State Athletic Commission executive director.

At a media conference earlier this year, Vargas shoved his future foe and was immediately surrounded by several of De la Hoya's men.

The two men will not come face-to-face until they touch gloves just before the first bell on Saturday night.

Felix Trinidad confirmed his retirement earlier this week and also voiced his opinion on the big fight.

Having defeated both men - De la Hoya by decision and Vargas by knockout - Trinidad knows quite a bit about the skills and weaknesses of both men.

The 29-year-old is predicting a victory for De la Hoya, but insists that he does not care for a rematch with either man.

Las Vegas welterweight Ishe Smith has the unique status of having sparred with both De la Hoya and Vargas.

So when he says he roots for and believes in a Vargas victory, maybe we should all run for the local betting shop.

"Fernando can do anything Oscar can do, and he's the bigger and stronger guy," said the unbeaten 24-year-old.

According to Smith, the Vargas camp had a much friendlier atmosphere while he admits to having had difficulties working with Team De la Hoya.

The promoters of the fight are already claiming that it is a sell-out on Saturday night.

The Mandalay Bay Hotel Events centre holds around 18,000 people and the fight is being broadcast on pay-per-view television in America for the not inconsiderable sum of $49.95.
