In 2014, MMA fighter Wanderlei Silva faced a ban for evading a drug test. The NSAC initially imposed a lifetime ban and fine. Silva challenged the decision, arguing lack of jurisdiction. A judge agreed, ordering a rehearing. The ban was reduced to three years, and the fine was rescinded. The case highlights anti-doping compliance and due process in MMA.
