Note: Before the main card begins tonight on HBO, Top Rank is streaming the undercard from Reliant Arena in Houston. Click here for more info.

Tonight, HBO has a big block of boxing including a series premiere, a big fight replay, and a live bout for the WBC middleweight title. Here's the lineup:

1. Cotto vs Margarito 24/7 (10 p.m. EST)
2. Pacquiao vs Marquez III replay (10:30 p.m. EST)
3. Julio Cesar Chavez Jr vs Peter Manfredo Jr

Chavez vs Manfredo is the live fight, it's going last. Early estimate for a start time is about 11:15, but it will probably be on at 11:30 or so. Still, I'd recommend tuning in at 11 if you aren't interested in seeing the Pacquiao vs Marquez replay, and just waiting it out from there. Mute may help.

Chavez (43-0-1, 30 KO) is the heavy favorite tonight against Manfredo (37-6, 20 KO), and the fight has met some criticism as an HBO main event. Chavez, 25, made his HBO debut in June, defeating Sebastian Zbik to win that WBC belt. He did good ratings, so he's back. But Manfredo being approved as an HBO opponent is also being questioned, and really, it's fair enough.

Still, I'm expecting an entertaining, fun fight to watch. Neither of them are "action stars," but they're both guys who come to fight and it could get interesting if Manfredo is really on his game.
