Jon Jones Vs Stipe Miocic Live Updates, UFC 309: McGhee Beats Martinez In Last Prelim Card Bout; Donald Trump In Attendance

The final prelim card bout of the event is now done and dusted. Marcus 'The Maniac' McGhee has defeated American compatriot Jonathan Martinez via unanimous decision in the bantamweight category. The scorecards read a uniform 29-28, 29-28, 29-28. And with that, it's time for the main card to get underway, even as United States president-elect Donald Trump makes his way into Madison Square Garden for witnessing the MMA extravaganza.

The next prelim card fight, between American MMA wrestlers Jim Miller and Damon Jackson, ends prematurely as Miller wins by submission in the first round. The 41-year-old adds to his UFC record by securing his 27th win. Up next, we have the bantamweight clash between Jonathan Martinez and Marcus McGhee.

Uganda's David Onama beats Mexican UFC debutant Roberto Romero by unanimous decision in their preliminary card lightweight bout. The scores read 40-37, 40-37 and 40-37. “I knew he was going to bring it and that kid put on a show tonight. But I am very happy. I’m glad I got this fight because at the start of the week I had no opponent. So I want to thank Roberto for that,” the victorious Onama tells Joe Rogan after the fight.

A bloodied Jhonata Diniz is stopped from competing in the third round of his preliminary card heavyweight bout against Marcin Tybura, and the Polish MMA wrestler thus wins the fight. Prelim card action continues as the lightweight bout between David Onama and Roberto Romero is underway.
