Viloria vs Marquez: Live stream, results, and round-by-round coverage

Tonight at 9 pm EST on WealthTV in the United States, GMA in the Philippines, and TV Azteca in Mexico, Brian Viloria and Tyson Marquez will unify flyweight titles, and Roman Gonzalez defends his 108-pound belt from the Los Angeles Memorial Sports Arena.

The fight can be streamed tonight for U.S. viewers on WealthTV.com.

Viloria (31-3, 18 KO) puts his WBO belt on the line against the WBA title title held by Marquez (34-2, 25 KO) in one of the best-matched fights of 2012, an under-the-radar hardcore fight fan special pitting the two best in one of the most exciting weight classes in the sport.

It's the rare fight that came together mostly because it's just a great fight, and the two fighters wanted to prove who the best man really is in the 112 pound ranks.

Gonzalez (33-0, 28 KO) has been excellent at 105 and 108 pounds in his career, and tonight the Nicaraguan WBA junior flyweight champ faces 22-year-old Mexican Juan Francisco Estrada (22-1, 18 KO). This could be tougher than expected. Though Estrada doesn't have any particularly big wins, his only loss came to Juan Carlos Sanchez Jr at flyweight. Sanchez currently holds the IBF super flyweight title.

Ryan Bivins will be handling the round-by-round and post-fight analysis duties for this show, so join him at 9 pm for what should be a very good night of fights. We'll also have live coverage of the Broner vs DeMarco card on HBO starting at 10 pm EST.
