Video: Brock Lesnar On Possible UFC Return, Failed UFC 200 Drug Tests

TMZ Sports caught up with Brock Lesnar at the WWE 2K17 Launch Party in New York City on Friday night (watch above), and asked the WWE Superstar about the possibility of another UFC comeback fight in the future.

"I’ve got a few challenges to overcome before I can get there but I don’t know," said Lesnar. "For right now I’m going to focus on my WWE career. I wanted to step back into the Octagon and avenge my loss to diverticulitis. Sunday, I’m facing Randy Orton and really that’s all that’s on my mind."

Lesnar also addressed his issues with USADA and the NAC regarding his two failed drug tests for his UFC 200 comeback fight last month. He said he's got a bumpy road ahead of him before thanking his UFC fans for their support and telling them they might see him in the Octagon again one day.
