Manny Pacquiao may get his revenge on main rival Juan Manuel Marquez soon enough. Both boxers have scheduled fights in the coming months, but they could meet shortly after.

On Oct. 12, Marquez will face Timothy Bradley for the WBO welterweight championship at the Thomas & Mack Center in Las Vegas. Six weeks later, Pacquiao will take on Brandon Rios on Mancu, China. If the two rivals are victorious, WBO president Francisco “Paco” Valcarcel says they should meet, once again, according to notifight.com.

"If Marquez and Pacquiao both win, the World Boxing Organization regulations would view the Filipino as [the mandatory] challenger to Juan Manuel,” Valcarcel said.

Pacquiao held the welterweight until he dropped it to Bradley last June. He went on to fight Marquez, never getting his rematch.

“Pacquiao goes against Rios for the WBO International title, while Marquez will attempt to capture the world welterweight championship of the WBO from Bradley,” Valcarcel continued. "If both win, the bout between them would be ready.”

A bout between Pacquiao and Marquez would be the fifth since 2004. Pac-Man won two consecutive after the first bout ended in a draw. In December, Marquez finally got the upper hand by knocking out Pacquiao in the sixth round. It was the second straight defeat for the 34-year-old, who hasn’t won in almost two years.

The oddsmakers seem to believe that a rematch between the two could be on the way. Pacquiao is a heavy favorite, according to Bovada, at minus-450. The bout between Marquez and Bradley is expected to be more highly contested, but the challenger is still a minus-155 favorite.

Valcarcel may be an advocate for Pacquiao-Marquez V, but doesn’t want to partake in fight No.5. He recently stated that he may have stepped inside the ring with his rival for the last time.

"I'd rather stay with the memory of that 'lucky punch' that I connected on Pacquiao,” said Marquez. “It's about pride and honor, not money. That's why in that contest there was no championship at stake, only the WBO's Champion of The Decade belt. There are no plans [to fight after Bradley]. We'll leave this commitment first, and then see. First I want to see how I feel and if I plan continue with my career."

Marquez doesn’t feel like he has anything to prove against Pacquiao. Pac-Man may have the 2-1-1 edge in the series, but Marquez has the only knockout.

"Pacquiao has been saying many things and immediately you can see that he wants me to take the bait, but he won't achieve that,” Marquez told Boxing Scene. “What he wants is a fifth fight, but it's not going to happen. I wish to leave this sport with the memory of knocking Pacquiao out after they stole three decisions from me. And [in the fourth fight] I showed who was the better fighter.”

Even if both fighters win their respective bouts, a rematch won’t be definite. Valcarcel says Pacquiao and Marquez will “have the last word.’
