Unwisely dismissing the observations of neurologist Dr. Rustico Jimenez, boxing legend Manny Pacquiao insisted he is “good” and apparently intends to continue fighting.

Roughly a month after the eight-division titlist was rendered unconscious by a spectacular overhand right thrown by WBO “Champion of the Decade” Juan Manuel Marquez, the president of the Private Hospitals Association of the Philippines expressed concern that Pacquiao (54-5-2, 38 KOs) is exhibiting initial signs of Parkinson’s disease.

During their fourth savage affair, “The Fighting Pride of the Philippines” 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, 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.

"I am doing good. God is good," said Pacquiao, 34, voted “Fighter of the Decade” for the 2000s by the BWAA. "I will be the one to say that I will retire from boxing because I am the one who knows and feels what my body is telling me."

Pacquiao, who pocketed in excess of $20 million for what amounted to his second consecutive defeat, had floored Marquez in the fifth and was leading 47-46 on all three judges’ scorecards at the time of the knockout.

Predictably, Pacquiao’s promoter, corruptible weasel Bob Arum, is determined to cement a fifth bout between the Filipino and Marquez for September.

Although the once fearsome southpaw will soon undergo tests at a brain clinic in Las Vegas, it has become readily evident that Pacquiao is a shopworn scrapper who needs to permanently shelve his gloves.

Manny Pacquiao needs to immediately say, “I will retire from boxing.”
