Before tonight's (Sat., Dec. 8, 2012) big "Pacquiao vs Marquez 4" HBO pay-per-view (PPV) event, which begins at 9 p.m. ET, a select portion of the under card offering of boxing bouts will stream live and free online from the MGM Grand Garden Arena in Las Vegas, Nevada.

Here are the two "super" fights, both of which are scheduled for eight rounds, fans will be treated to for tuning in early (7 p.m. ET:

• Super Bantamweight (124 lbs.): Dodie Boy Penalosa Jr. (9-0) vs. Jesus Lule (6-4)
• Super Featherweight (127 lbs.:): Ernie Sanchez (13-3) vs. Coy Evans (10-1-1)

Penalosa is an undefeated (9-0) Filipino fighter who has registered a knockout each time out, while Lule is currently riding a four-fight unbeaten streak, all in 2012.

In the opening bout, Sanchez -- another Filipino fighter (see a pattern here?) -- was featured on the undercard of Manny Pacquiao's last PPV, defeating Wilton Hilario via unanimous decision. Evans, meanwhile, is eight years older than Sanchez, looking to bounce back from a loss his last time out against another up-and-comer, Danny Aquino, back in March.

Immediately after the under card finishes up, the main card kicks off on PPV from "Sin City," which MMAmania.com will have complete blow-by-blow, round-by-round coverage of before, during and after the event. CLICK HERE to get ongoing live coverage of all the night's action.
