The United States Anti-Doping Agency has acknowledged a recent "technical glitch" led to inaccurate data on UFC athlete Brock Lesnar appearing on its public website.
Per company policy, USADA updates all testing data to a public website throughout the year. This Athlete Test History database does not include results, but indicates how many times a UFC athlete -- or Olympic athlete -- has been tested that year.
An update in mid-October showed Lesnar had submitted six tests in 2018, however that number recently changed to five. According to USADA, the original update was flawed and the current figure reflects the accurate number. At this time, it appears Lesnar was the only athlete affected.
"USADA updates the Athlete Test History page of the UFC/USADA website on a weekly basis," stated USADA spokesperson Adam Woullard. "During an update on the week of October 15th, we experienced a technical issue that resulted in the information on the page being displayed incorrectly.
"The correct test history for the athlete is one test [that week], not two. The issue has been fixed and the testing numbers on the website are all accurate. We are still investigating the specific technical issue that led to the error."
Jeff Novitzky, UFC Vice President of Athlete Health and Performance, told ESPN the promotion has no concerns regarding the issue.
"I have access to a more specific database than the public, which displays the date a sample is collected, what type of sample it is and what the results are as soon as they are available," Novitzky said. "The public website, as I understand it, indicated there had been two tests during this last quarter, and it recently dropped to one. I have always seen one test in this quarter for Lesnar. It was a urine test and it came back negative."
Lesnar, 41, is a WWE star and former UFC champion. He has not fought for the promotion since 2016. He re-entered the UFC's testing pool in July, in anticipation of a potential heavyweight title fight against Daniel Cormier in 2019. He will be eligible to compete on or after Jan. 8, 2019.
In 2016, Lesnar tested positive for the banned substance clomiphene, in a test administered by USADA, prior to a non-title bout against Mark Hunt at UFC 200. He was ultimately suspended for one year and fined $250,000 for that failed test.
Novitzky said he is comfortable with how USADA has tested Lesnar since his re-enrollment in the program five months ago.
"This program has a limited amount of resources and funding," Novitzky said. "It would be great to test everybody every week, but that would cost millions and millions of dollars. To put it in a nutshell, I have all the confidence in the world USADA is allocating these testing resources appropriately."
