A Nevada Athletic Commission pre-fight medical questionnaire signed by Floyd Mayweather reveals the boxer had Kenalog injections in his hands at 5 am the day before his bout with Conor McGregor.
According to Drugs.com Kenalog is classified as a Glucocorticoid which are banned by the World Anti Doping Agency (WADA) in-competition.
So is this a doping violation? No.
The questionnaire is unclear what type of injection occurred but assuming it was intra-articular as opposed to intramuscular it does not meet the above prohibited administration methods.
Regardless of the manner of injection, WADA’s Prohibited List (which is adopted by the Nevada Athletic Commission) only bans Glucocorticoids in-competition.
As was learned by the Nate Diaz Vaping incident, Nevada and the United States Anti-Doping Agency (who were privately retained to conduct anti-doping for this bout) follow WADA standards when defining in-competition.
WADA has the following definition of in-competition ingestion:
In-Competition: Unless provided otherwise in the rules of an International Federation or the ruling body of the Event in question, “In-Competition” means the period commencing twelve hours before a Competition in which the Athlete is scheduled to participate through the end of such Competition and the Sample collection process related to such Competition.
USADA uses a similar definition:
In-competition refers to the period commencing twelve hours before a competition in which the athlete is scheduled to participate through the end of the competition and the sample collection process related to the competition.
The NAC, when debating harsher (and consistent) anti-doping penalties published this document implying they follow (and will continue to follow) the WADA in-competition definition:
We will continue to follow WADA’s definitions, particularly the definition of “In‐competition.
