Having not applied for a reissued boxing license, speculation is mounting that Manny Pacquiao will throw fists with WBO “Champion of the Decade” Juan Manuel Marquez for a fifth time in September at a venue outside of the United States.

"We haven't received any application for 2013," NSAC executive director Keith Kizer is quoted as saying by abs-cbnnews.com.

During their fourth savage affair in December, Pacquiao (54-5-2, 38 KOs) was knocked onto Queer Street by the 39-year-old Marquez (55-6-1, 40 KOs) at 2:59 of the sixth round.

In a genuinely scary scene, the 34-year-old Pacquiao, who had controversially earned a draw and two conquests over the ballooned Mexican since their first meeting in May 2004, remained motionless on the canvas for several minutes.

Accordingly, “The Fighting Pride of the Philippines,” who neurologist Dr. Rustico Jimenez recently observed is exhibiting initial signs of Parkinson’s disease, had his license suspended for 120 days by the Nevada Boxing Commission.

Entirely dismissing the concerns of the president of the Private Hospitals Association of the Philippines, Pacquiao’s promoter, corruptible weasel Bob Arum, remains determined to cement a fifth clash between the eight-division titlist and Marquez.

The “Fighter of the Decade” for the 2000s by the BWAA, whose ban to battle in Las Vegas concludes in March, is considering clashing with Marquez in Dubai, Mexico, Singapore or China.

"He [Pacquiao] says that he doesn't want to fight in the United States because of the high taxes, which I can hardly blame him and you know Marquez faces the same high taxes,” said Top Rank chief Arum, 81. “The administration didn't help raising the tax rates from 35% to 39.6%. You know, there's a limit to what these guys wanna pay, you know, that's almost 40% of his purse going for taxes, that's a lot."

Pacquiao, who pocketed in excess of $20 million for what amounted to his second consecutive defeat, has fought his last four bouts in “Sin City” and his last 12 in America.

Unfortunately for the once-fearsome southpaw, it’s moot where Pacquiao next tussles because the shopworn pugilist needs to permanently shelve his gloves.

If the famed Filipino doesn’t retire from the sport that helped him earn millions of dollars, Manny Pacquiao will likely become boxing’s next tragic figure.
