Manny Pacquiao Undergoes Blood Testing 20 Days Before Clottey Bout?

Does it mean anything? Should it mean anything?

For boxing enthusiasts, it just might.

GMA News today released a report showing Manny Pacquiao (50-3, 38 KO) undergoing a routine physical prior to his bout with Joshua Clottey (35-3, 20 KO) on March 13, in which he is seen to undergo blood testing.

The camps of Pacquiao and rival Floyd Mayweather Jr. (40-0, 25 KO) recently forced the collapse of a pound-for-pound super-fight when they failed to agree upon a timetable for Olympic-style testing, which Mayweather Jr. now insists upon before every bout.

Pacquiao was amenable to random blood and urine testing taking place before and directly after the bout, but insisted on a cut-off date for testing at least 24 days before the fight. He cited his belief that the drawing of blood too close to the bout would affect his training and performance.

Since the collapse of negotiations, Pacquiao has lined up strong welterweight Joshua Clottey as a replacement opponent for March, while Mayweather will face the experienced Shane Mosley (46-5, 39 KO) on May 1.

Yet there is still hope among many boxing fans that the camps of Pacquiao and Mayweather Jr. can come to a compromise in the future for what is expected to be the biggest fight in recent decades.

Should the footage be taken as a sign of movement from Team Pacquiao? Or is it already too late to salvage hope for the fight most boxing fans wish to see?
