We all know that Manny Pacquiao and Juan Manuel Marquez will meet for the fourth time on Dec. 8 (HBO PPV) at the MGM Grand in Las Vegas. But what else will you get if you decide to shell out the $50 or $60 to buy the pay-per-view? Here is what you can expect the undercard to look like, according to Top Rank, although the bouts are not finalized yet:

• Former featherweight titlist Yuriorkis Gamboa (21-0, 16 KOs), who left Top Rank when rapper 50 Cent, an aspiring promoter, bought out his contract for seven figures earlier this year, will be on the card under a deal struck between 50 and Top Rank. If the fight is finalized, Gamboa -- idle since September 2011 after pulling out of a fight earlier this year with Brandon Rios and because of the snit with Top Rank that led to the sale of his contract -- would face Mexico's Miguel Beltran Jr. (27-2, 17 KOs) for a vacant interim junior lightweight belt. Beltran is coming off a split decision loss to Roman “Rocky” Martinez for a vacant title in an all-action slugfest on the Sergio Martinez-Julio Cesar Chavez Jr. undercard on Sept. 15.

• Lightweight titleholder Miguel Vazquez (32-3, 13 KOs) of Mexico, who retained his belt with a split decision win against mandatory challenger Marvin Quintero last Saturday night in the opening bout of an HBO tripleheader, is being lined up to face the Philippines’ Mercito Gesta (26-0-1, 14 KOs) in a fight that has been in the works since before Vazquez even faced Quintero.

• Dynamic featherweight prospect Javier Fortuna (20-0, 15 KOs) of the Dominican Republic likely will face upstate New York-based Ireland native Patrick Hyland (27-0, 12 KOs) for a vacant interim featherweight belt.
