Pacquiao vs. Marquez and 5 Upcoming Rematches You Don't Want to Miss

The second half of 2011 is set to showcase several rematches, including the mega-matchup between pound-for-pound king Manny Pacquiao and Juan Manuel Marquez.

The Filipino icon will be taking on Marquez for the third time on Nov. 12, but he is going in as a heavy favorite and hasn't lost a fight to him despite fighting him twice before. Their first meeting was ruled a draw, while Pacquiao was seen getting the victory in the second fight by split-decision.

After Floyd Mayweather's controversial, but decisive victory over Victor Ortiz, it's up to Pacquiao to out-perform him and get a clear victory over his opponent.

Along with that fight, there will be several rematches being fought throughout the rest of the year, and these are the five best ones that you don't want to miss.

No. 5: Hernan "Tyson" Marquez vs. Luis Concepcion

Hernan "Tyson" Marquez (32-2, 24 KO) won the WBA World Flyweight title from Luis Concepcion (23-2, 18 KO) earlier this year in a very fan-friendly and fight of the year type of fight that saw each boxer hit the canvas.

Both boxers were dropped in the first round, and Concepcion would go down two more times before losing by TKO in Round 11.

Marquez, who is on a four-fight win streak, will defend his title for the third time at the October 29 event in Sonora, Mexico.

Concepcion recently rebounded from the loss to knock out Manuel Vargas in the very first round.

This could be the fight that sets up a rubber match to a very memorable trilogy.

No. 4: Celestino Caballero vs. Jonathan Victor Barros

The first fight between Celestino Caballero (32-4-1, 23 KO) and Jonathan Barros (33-1-1, 18 KO) was not short of controversy in July.

After knocking down Barros twice throughout the 12-round title bout, and appearing to be in complete control of the fight, Caballero lost a split-decision. Barros retained his WBA World Flyweight title and increased his win streak.

Barros' only defeat is to Yuriorkis Gamboa, and if not for his hometown decision, he would have a second loss to Caballero.

Caballero was considered to be a top 15-20 boxer before losing two fights in a row. He will go back to Argentina to try to pick up the title, but he may be in for another hometown decision versus his opponent.

No. 3: Andy Lee vs. Brian Vera

Andy Lee (26-1, 19 KO) only has one loss on his record, and it was to the opponent he faces on Oct. 1, Brian Vera (19-5, 12 KO).

The bout will be broadcast on the undercard of Sergio Martinez vs. Darren Barker on HBO.

Since defeating Lee in 2008, Vera has gone 3-4 with one of his wins coming against Sergio Mora on "Friday Night Fights."

Lee has gone 10-0 since the loss and had an impressive come-from-behind victory against Craig McEwan in March. His last victory was against Alex Bunema.

This match could offer up many surprises, and it's unsure of who has the most momentum behind them going into the fight despite their records.

No. 2: Antonio Margarito vs. Miguel Cotto

Rematches do well when controversy surrounds the first fight, and the bout between Antonio Margarito (38-7, 27 KO) and Miguel Cotto (36-2, 29 KO) will give fans lots of answers about the first meeting between the two.

When they first met in 2008, Cotto was undefeated and looking to capitalize on his star-status with a win over the most avoided boxer in Margarito.

"The Tijuana Tornado" stopped Cotto in Round 11 and got the biggest victory of his career. Since that win, he has gone 1-2 with brutal losses against Shane Mosley and Manny Pacquiao.

Even more important than the losses, a year-long suspension from the sport for Margarito marred his career after he attempted to fight with loaded gloves in his bout with Mosley.

Many have been quick to question his victory over Cotto and if he had loaded gloves in that fight. Either that or he was just the better fighter. Everyone will find out on Dec. 3 when the bout goes down on HBO pay-per-view.

No. 1: Manny Pacquiao vs. Juan Manuel Marquez

Manny Pacquiao (53-3, 38 KO) and Juan Manuel Marquez (53-5-1, 39 KO) will meet for a third and final time on Nov. 12, and it could be the match that sets up a mega-fight between Pacquiao and Floyd Mayweather Jr.

Pacquiao needs to make it past Marquez, and that's no easy task as their first two fights proved. They first met in 2004 where the fight was scored a draw after Marquez was knocked down three times in the first round, and put on the comeback of his life to win enough of the remaining rounds to make it even.

Their second bout from 2008 saw Marquez getting dropped again and fighting back to lose a hard-fought split-decision that many thought he had won.

Since that victory, Pacquiao has gone 7-0 with wins over Shane Mosley, Miguel Cotto, Ricky Hatton, Joshua Clottey, David Diaz, Antonio Margarito and Oscar De La Hoya.

Marquez has gone 5-1 with big wins over Michael Katsidis and Joel Casamayor. His loss was against Floyd Mayweather in 2009.
