British star Amir Khan (31-3, 19KOs) is preparing for his the biggest fight of his career, on May 7th, when he challenges Saul 'Canelo' Alvarez (46-1-1, 32KOs) for the WBC middleweight championship.

Khan will jump up by eight pounds, from 147 to 155-pounds, to make the fight take place.

The T-Mobile Arena in Las Vegas will host the contest and HBO Pay-Per-View will carry the event.

Many insiders believe the increase in weight, along with the fact that there is no rehydration clause, is going to place Khan at a big physical disadvantage on the night of the fight.

Khan is not bothered by the weight. He feels the contracted catch-weight is actually a positive that adds excitement and intrigue to the contest.

"What makes this so exciting is the weight. Obviously being a 147-pound fighter, and moving up to 155, nearly two weight divisions to take this fight and hopefully take the title away from Canelo. This is something that can make history and that's what I'm here to do. I want to make history like I did in 2004 in the Olympics," Khan said.

For the first time in his career, Khan is a very big underdog. For Khan, the scenario with Canelo is a replica of his run in the Olympics, where very few expected him to win a medal. He sees the fight with Canelo as another opportunity to pull off a stunning achievement where the odds are stacked against him.

"Nobody thought that I would make history in the Olympics. I was a young boy going up against men. Now I'm here, 29 years old, against Saul Alvarez - who is supposed to be a very dangerous opponent. He's a world champion at middleweight. I'm going to his weight, I'm going to the lion's den...his backyard, and I'm going to beat him there."
