Should Manny Pacquiao have “an exciting and impressive win” over once-beaten contender Brandon Rios, and Floyd Mayweather Jr. defeat RING 154-pound champion Saul “Canelo” Alvarez, the Filipino star would still be open to a bout with Mayweather, said Pacquiao’s advisor, Michael Koncz.

Mayweather meets Alvarez on Sept. 14 at the MGM Grand in Las Vegas, while Pacquiao takes on Rios on Nov. 23 in Macau (Nov. 24 in China).

Pacquiao is trying to rebound from consecutive losses to WBO welterweight titleholder Tim Bradley in June, and Juan Manuel Marquez in December.

“Right now, Manny’s focused on Brandon Rios, but Floyd is always a possibility. We’ve always said that we would fight Floyd,” said Koncz.

“I think that Manny will have to have an impressive win in light of comments that Floyd has made about Manny losing his last two fights, and I think that if Manny has an exciting and impressive win come Nov. 24, then Floyd won’t have any excuse if he really wants to fight.”

Marquez and Bradley elected to fight each other — instead of Pacquiao — on Oct. 12 at the Thomas and Mack Center in Las Vegas.

“In my personal opinion, with my time spent with Manny, I don’t think that Bradley or Marquez are anywhere in his memory banks,” said Koncz. “We gave them an option, and we were intending to pay then fairly, and they chose not to fight us, so that’s their loss, not ours.”

Mayweather, whose past differences with Pacquiao over drug testing contributed to failed negotiations for a megabout, has employed random drug testing by the United State Anti-Doping Agency (USADA) for his past four victories: Shane Mosley by unanimous decision, Victor Ortiz by fourth-round knockout, and both Miguel Cotto and Robert Guerrero by unanimous decision. 

Pacquiao and Rios have contractually agreed to be randomly drug tested by The Voluntary Anti-Doping Association (VADA).

“Manny came out and said that he would agree to the testing, and that he would give Floyd a 60-40 split,” said Koncz, who also does not believe that Mayweather’s multi-fight deal with Showtime — Pacquiao has mostly fought on HBO — will be a factor.  “Manny’s not tied to to any network, so if the fans still want to see this fight, we’re willing to do it.”
