All 32 fighters who appeared on boxing cards held Oct. 11 and Oct. 12 in Las Vegas came up negative for the banned substances tested for in Nevada’s drug-screening panel, according to an email from state athletic commission Executive Director Keith Kizer.
In addition, the headliners of the Oct. 12 show — Timothy Bradley and Juan Manuel Marquez — were also negative under additional, enhanced testing done for their bout, according to a report by Kelsey McCarson of TheSweetScience.com.
“Kizer said each fighter was randomly tested four times (both blood and urine) during the NSAC program, and that Carbon Isotope Radiation (CIR) screening to detect the use of synthetic testosterone was done on half of the urine samples collected. No synthetic testosterone was discovered in either fighter,” McCarson wrote.
The testosterone to epitestosterone ratios for Bradley and Marquez were never higher than 1.1 to 1, which is below the 4:1 maximum level of the World Anti-Doping Agency’s standards. Nevada used to have a 6:1 maximum but changed to a 4:1 maximum in early September, according to McCarson.
Bradley also was negative in drug testing done by the Voluntary Anti-Doping Association, or VADA. That is the same agency by which Nonito Donaire is randomly tested year-round, and the agency that will be conducting the testing for next month’s fight involving Manny Pacquiao and Brandon Rios. It was through VADA testing that Andre Berto and Lamont Peterson came up positive for banned performance enhancing drugs in 2012.
Among the other 14 fighters to appear on the Oct. 12 show at the Thomas and Mack Center were Orlando Salido, Orlando Cruz and Vasyl Lomachenko.
The Oct. 11 show, held at that same arena, was headlined by a bout between Jessie Vargas and Ray Narh, and also had Jessie Magdaleno on the undercard.
