Top Rank's CEO Bob Arum is seriously considering the possibility of a fight between Brandon Rios (31-0-1, 23KOs) and the winner of the upcoming welterweight clash between Manny Pacquiao and Juan Manuel Marquez, which takes place on December 8th at the MGM Grand in Las Vegas.

The real target, in terms of action, is Pacquiao vs. Rios. Even if Pacquiao is defeated in December, a fight with Rios could still be made.

"Pacquiao and Rios would be an unbelievably huge draw because people would know that they would see crazy, wild action," Arum said.

Rios is willing to fight Pacquiao at any weight between 140 and 147-pounds, says Arum. Rios returned to the ring on Saturday night at the Home Depot Center in Carson, California - and he stopped Mike Alvarado in the seventh round of a classic back and forth war.

"Obviously I would have to first talk with Pacquiao and Marquez but I would think that it would be a big possibility [for Rios to fight the winner] - and if we can't do it than maybe we'll do a rematch [with Alvarado]," Arum said.

There will be pressure to proceed in a different direction, Arum admits. Fans are already demanding a rematch between Rios and Alvarado - but staging an immediate rematch is a risky business move when a major fight with Pacquiao or Marquez is hanging in the balance. Pacquiao has a tentative date of April 20th for his next fight.

"Yeah there is pressure [to do a Rios-Alvarado rematch], but obviously boxing is a business. And if there is a possibility of Rios fighting Pacquiao or Marquez for really bonanza money, how can you take the risk by putting him in with Alvarado again where he may lose out on that payday," Arum said.

And, Arum is not ruling out the possibility of a fight between Pacquiao and Floyd Mayweather Jr. in the first half of 2013. If Mayweather comes to the table, then he is the first priority above anything else.

"Mayweather is always the first choice. These stupid assh**es that say I'm standing in the way of that fight....what are they talking about?," Arum said.
