Pacquiao v Marquez 4: All fighters test negative

In the light of a recent blood test failure at a major boxing event, the results from the recent Fight of the Year contender involving Juan Manuel Marquez and Manny Pacquiao, along with the undercard have come back clean.

As the super-bantamweight title bout between Guillermo Rigondeaux and Poonsawat Kratingdaenggym fell by the wayside due to an undisclosed problem, it is has now been confirmed that the high-profile MGM card registered no incidents.

A section of doubters, including Pacquiao’s trainer Freddie Roach, had speculated that ‘Dinamita’ looked more muscular than usual in the build-up to their fourth fight, eluding to possible drug use, although Keith Kizer has confirmed nothing untoward came back in any test.

Marquez, 39, scored his biggest victory to date last weekend as the three-weight world title holder stunned the Filipino with a crushing right hand that ended the contest in the sixth, and may now be ready to meet his main rival for a fifth time next year.
