He looked straight into the camera and said, "Brock Lesnar, you want to know what it feels like to get your ass kicked by someone 40 pounds lighter? Meet me in the Octagon."
One Las Vegas sportsbook is already taking wagers on the potential superfight.
On Sunday, the Westgate Las Vegas SuperBook opened odds on the potential bout with Jones a -300 favorite and Lesnar +250.
Westgate sportsbook manager Jeff Sherman told ESPN that there was strong initial support for Jones, pushing him up to -450. The odds as of Monday morning were Jones -360, Lesnar +280.
Lesnar is currently retired and would need to serve out the rest of his one-year suspension from failing a doping test at UFC 200 last year.
UFC president Dana White noted the potential hurdles on Saturday night. "It would take six months for Lesnar to even go through USADA to fight," White said. "So it's fun to talk about, but the reality of it happening anytime soon, it's not a reality."
The fight must happen by Dec. 31, 2018, and be a UFC match for action. Wagers at Westgate will be refunded if the fight doesn't occur by that date.
