New Delhi: In a shocking new development, UFC on Saturday revealed that WWE superstar Brock Lesnar was being investigated by the United States Anti-Doping Agency (Usada) over a potential failed drug test.
Lesnar recently made an appearance at UFC 200 on July 9, beating Mark Hunt in a heavyweight fight.
The possible violation however was detected in an out of competition test on 28 June, reported the BBC.
"We will get to the bottom of this," Lesnar told AP.
A UFC statement said: "Usada will handle the results management and appropriate adjudication of this case.
"It is important to note that, under the UFC anti-doping policy, there is a full, fair legal review process that is afforded to all athletes before any sanctions are imposed."
The 39-year-old, who made a whopping 2.5m (£1.9m) thanks to his UFC fight, is expected to return to the WWE next month.
