All sports – and currently combat sports – have a learning curve when it comes to transitioning to the heightened scrutiny of random independent drug monitoring (including urine and blood).
It may be new to the many fans, athletes and camps of MMA and professional boxing, but Olympic sports, track and field, and international cycling have lived with the potential “knock at the door” for decades.
With any learning curve, rough patches will be encountered, and mistakes will be made. But that shouldn’t be an acceptable excuse to delay the inevitable.
