BoxingScene.com has learned that tonight's lightweight championship contest at the Beau Rivage Theatre in Biloxi, Mississipi, between IBF/WBO/WBA lightweight champion Nate Campbell (32-5-1, 25 KOs) and Joan Guzman (28-0, 17 KOs), is still in doubt.

Guzman was 3.5-pounds (138.5) over the lightweight limit during yesterday's weigh-in. He was given two additional hours to make the weight,  never came back to for a second attempt. One source told BoxingScene that Guzman was very dehydrated and went to the hospital last night to get fluids back into his body.

The word on the street in Mississipi is that Guzman's camp is contemplating his withdrawal from the fight because of his physical state. BoxingScene has heard that Guzman's camp was told by the Mississipi State Athletic Commission that if their fighter pulls out, he could be looking at an indefinite suspension, because there is a general  feeling that Guzman and his team had to have known days before the weigh-in that a potential problem existed with making the lightweight limit.

If a fight happens to go forward, Guzman may be asked to step on the scales to check his current weight. If Guzman is considerably bigger than Campbell, that could be a whole other issue in itself. A final decision will probably come down in the next 2-3 hours.
