Today's weigh-in at the MGM Grand in Las Vegas for tomorrow's Manny Pacquiao vs Juan Manuel Marquez fight on HBO pay-per-view went by almost without a hitch.

For the main event, with a contracted weight of 144 pounds, Manny Pacquiao weighed in at 143, while rival Juan Manuel Marquez tipped the scales at 142. Both looked to be in very good shape, and Marquez at 142 looked much leaner and stronger than he did back in 2009, when he weighed in the same for a fight with Floyd Mayweather. Whatever concerns there are, the addition of strength and conditioning coach Angel "Memo" Heredia/Hernandez has obviously made a difference for Marquez this time around.

Casamayor Heavy

The main co-feature bout had some mild drama, as 40-year-old Cuban veteran Joel Casamayor was one pound over the junior welterweight limit of 140 pounds for his fight with Timothy Bradley. While Bradley's six pack was as prominent as ever as he hit the weight right on the button, Casamayor looked dried out and soft at the same time on the scales, weighing in first in briefs, second nude, and third nude while sucking his stomach in. Each time, he was at 141. He has an hour to make weight, which probably won't be a big deal. But either way, that fight will go on.

Junior welterweights Mike Alvarado and Breidis Prescott both weighed 140 pounds for their fight, and in the pay-per-view opener, Luis Cruz is at the super featherweight limit of 130 pounds, while Juan Carlos Burgos weighed 129.
