Williams vs Lara Weights: Main Eventers On Point, Arreola at 236

Tomorrow night's HBO show hasn't garnered the buzz that Showtime's double-header has, but both fights are interesting and the off-TV undercard has some highlights, too.

In the junior middleweight main event, Paul Williams (39-2, 27 KO) moves back down in weight and returns from an ugly knockout at the hands of middleweight champion Sergio Martinez, facing Cuba's Erislandy Lara (15-0-1, 10 KO). Williams weighed in at 153½, while Lara was a full pound below the limit at 153.

The televised co-feature is a great change of pace for American boxing broadcasts, as 122-pound titlist Akifumi Shimoda (23-2-1, 10 KO) makes the first defense of his WBA belt by coming to the States to face Rico Ramos (19-0, 10 KO). It will be Shimoda's second fight outside of Japan (he fought in Mexico in 2009), and Ramos' first shot at a major title. Shimoda weighed in at 121½, with Ramos at 122.

After the jump: Chris Arreola and Jhonny Gonzalez.

Heavyweight contender Chris Arreola and featherweight titlist Jhonny Gonzalez highlight the untelevised undercard. Arreola (32-2, 28 KO) continues to hover in the mid-230s, coming in at 236 pounds for his fight with Friday Ahunanya (24-7-3, 13 KO). Ahunanya, 39, weighed in at 244½.

Gonzalez (48-7, 42 KO) is making the first defense of the WBC 126-pound belt he won in April, facing Mexican veteran Tomas Villa (23-7-4, 14 KO). Villa was run over in the first round by Mikey Garcia back in April 2010, and hasn't fought since June 2010. He may be best remembered for his epic war with Rogers Mtagwa in 2008, the final main event of the "old" Solo Boxeo Tecate. Gonzalez and Villa both weighed 125½.
