He's willing to fight anyone, at any time. No running, no fancy boxing. Lots of big punching.

All he asks is that it's a fair fight.

Jose Luis Castillo wouldn't give him one when the two were supposed to meet for a third time in June. When Castillo failed to make weight for the second straight time, Corrales walked away from a US$1.3 million payday.

It wasn't easy, but Corrales believes it was the right thing to do.

``I stood on level ground and explained to everybody if he didn't make weight there wouldn't be a fight,'' Corrales said. ``I made the right decision.''

Corrales returns to the ring Saturday night for the first time in nearly a year, and this time his opponent's weight shouldn't be a problem. Joel Casamayor knows something about making weight because a fighter didn't eat if he didn't make weight when boxing for the Cuban national amateur team.

Instead, it may be Casamayor's left hand that is the problem. He's already used it to knock Corrales down three times in their two previous fights, and is confident it will happen again.

``Corrales won't see the 12th round,'' Casamayor said. ``The knockout will come.''

Corrales, who gained fame in a May 2005 fight against Castillo that has already become legendary, meets Casamayor in the scheduled 12-round fight from the Mandalay Bay hotel-casino. The fight will be televised on Showtime on a card that begins at 9 p.m. ET.

Both fighters have a lot at stake. For Corrales, it's proving that his knockout loss to Castillo in their rematch was a fluke. Casamayor, meanwhile, must show he still has his superb boxing skills and reflexes at the age of 35.

``I expect a war out of him,'' Corrales said. ``For some reason they find glory and their old youth when they fight me.''

Casamayor (33-3-1, 21 knockouts) stopped Corrales the first time they met, knocking him down twice and finally winning in the sixth round when bleeding caused by a faulty mouthpiece left Corrales swallowing blood. But Corrales also knocked Casamayor down in that fight, and came back to win a decision by outboxing him in their second fight.

He is a 2-1 favourite this time in the fight for the WBC lightweight title, but the crafty Casamayor believes the odds should be reversed.

``I learned that this guy (Corrales) comes one direction _ forward. He is a one-dimensional fighter,'' Casamayor said. ``I can beat him any way. I feel like I won both fights. I know him like my own son.''

Corrales (40-3, 33 knockouts) has had a year to recover from his fourth round knockout by Castillo, a break caused largely the failure of Castillo to make weight for their third fight. Castillo also didn't make weight in the second fight, but Corrales went on and fought him anyhow.

It proved a mistake, when Castillo overwhelmed him with a left hook that floored Corrales.

Corrales had stopped Castillo in the 10th round of their first fight, an epic affair in which he was down twice in the round only to come back with a flurry of punches to win the fight in a stunning ending to a brutal bout.

``Everybody talks about that fight. For many, many years to come that's going to be the conversation piece,'' Corrales said. ``People will look at it and say that was the best fight they had ever seen. For our day and age you don't see that kind of fight anymore.''

Casamayor is a throwback of sorts himself. The lefty was a gold medallist for Cuba in the 1992 Olympics, which got him a pig from Fidel Castro as a reward. He's a technically sharp fighter who has never been afraid to mix it up or use a few questionable tactics learned through a long career in the ring.

``I feel strong, better than I have ever felt,'' Casamayor said. ``The fight won't last 12 rounds.''
