Meanwhile, co-main eventers ONE bantamweight kickboxing world champion Jonathan Haggerty and his challenger, Chinese megastar Wei Rui, had a short back-and-forth, which concluded with Wei stating:

"Bring it on! I hope he brings it. Because I don't think he's on my level. I'd suggest he steps up."

These two ONE world championship bouts will close out a 14-fight card at the Lusail Sports Arena in Lusail, Qatar, on Thursday, Feb. 20.

Tickets are available via Q-Tickets.
