The Mexican's A sample has tested positive for banned substance Zilpaterol, and the WBC will now follow their protocol to see whether or not Nery has broken their rules.
If he has there is a good chance that the WBC would strip Nery and give the title back to Yamanaka, who would bizarrely tie the long standing record of most world title defenses by a Japanese fighter with a No Contest essentially acting as his 13th defense. There is also the possibility that the WBC accept that Nery has ingested the chemical by accident, though this could be a really controversial stance given the way they have treat other fighters in the past. This is actually with in the rules of the "Clean Boing Program", under section V subsection H-
- For the avoidance of all doubt, because issues may arise as to whether: (i) a boxer’s exposure to prohibited substances was intentional; (ii) such substance(s) provided the boxer with a competitive advantage; (iii) the testing procedure was reliable; (iv) other factors should be considered; the WBC does not therefore employ or adhere to a “strict liability” standard in anti-doping matters. In each case, the WBC may in its discretion consider all factors in making a determination regarding responsibility, relative fault, and penalties, if any.
