Featherweight contenders will collide in the UFC main event on June 17. Josh Emmett will compete in his second promotional main event when he takes on Ilia Topuria , who will compete in his first five-round UFC fight. The event does not currently have a known location or venue. A person with knowledge of the situation confirmed the booking to MMA Junkie but asked to remain anonymous as the promotion has yet to make an official announcement. User @KOlmeneroMMA broke the news on Twitter. Emmett (18-3 MMA, 9-3 UFC) looks to bounce back from a UFC 284 submission loss to Yair Rodriguez in February.
