USADA Releases Testing Results for Floyd Mayweather vs Victor Ortiz


by Hans Olson

Here are the results for the Mayweather/Ortiz USADA testing, just released today. I’ve included the Mayweather/Mosley results from May 2010 as to show that there are not specific dates that USADA does or does not test on. The testing, and the integrity of it speaks for itself. More info can be found on www.usada.org

USADA posts test statistics on a quarterly basis, by sport and by athlete, as soon as possible following the completion of each calendar quarter.

In response to a high volume of interest in the testing statistics for the professional boxing event held on September 17, 2011 between Floyd Mayweather, Jr. and Victor Ortiz, the following is a summary of program information:

Both Mayweather and Ortiz were tested a total of ten times by USADA between July 17, 2011 and September 17, 2011, with nine of the sample collections occurring with no advance notice leading up to the fight, and the tenth occurring immediately following the fight. All ten of each athlete’s USADA sample collections included urine, and five of these collections for each fighter also included blood testing.

Collections were conducted using a balanced test distribution schedule, and with no allowances for black-out or cut-off dates.
