Tonight's HBO split-site double-header will go live at 10:30 p.m. EST, with a pair of title fights coming your way.

In the main event from Mexico City, young phenom Canelo Alvarez (38-0-1, 28 KO) will defend his WBC junior middleweight title against declining Puerto Rican Kermit Cintron (33-4-1, 28 KO).

Cintron, 32, is coming off of a pair of uninspired efforts in July and August, first getting routed by Carlos Molina, and then slipping past Antwone Smith. If Cintron is his old self -- or some approximation -- he could be a bit more trouble than Golden Boy believed he was when they signed him up for this one, because Alvarez, 21, wasn't exactly flawless last time out either, a win over Alfonso Gomez in September.

In the co-feature, Cincinnati's own Adrien "The Problem" Broner (21-0, 17 KO) looks to grab the vacant WBO super featherweight strap against Argentina's unknown Vicente Rodriguez (34-2-1, 19 KO). There will also be highlights from featherweight prospect Gary Russell Jr (18-0, 10 KO), who faces veteran Heriberto Ruiz (47-11-2, 29 KO) on the undercard. Russell was originally slated to fight Dat Nguyen, on TV, but when Nguyen pulled out, Russell lost his live spot.

We'll have live, round-by-round results of both of the main fights, with immediate post-fight analysis coming after. And don't forget that Cotto vs Margarito 24/7 precedes the live fights at 10 p.m. EST, and last week's episode was, in my view, the best episode in the entire history of the series, so you might want to tune in early.
