Brock Lesnar beat Mark Hunt at UFC 200, landing 137 strikes in the process, according to Fight Metric. Five days later, the UFC was informed by its anti-doping partner USADA that Lesnar tested positive for performance-enhancing drugs — from a sample that came more than a week prior to UFC 200.
USADA did not get the test result back until July 14, according to the UFC. That timeframe between the sample collection and the result returning is standard in the industry.
However, USADA could have gotten the results back quicker had the agency requested it be expedited.
