At the end of 2024, the expectation was Shavkat Rakhmonov would be the first challenger for UFC welterweight champion Belal Muhammad. But injury to Rakhmonov led to opportunity for Jack Della Maddalena, who was thrusted from planned Fight Night London main event to a title shot.

And JDM has made the most of his sudden opportunity, defeating Muhammad in a major upset to become the new UFC welterweight champion in the main event of UFC 315 in Montreal.

By round three, Della Maddalena was in a solid flow, connecting at will on the defending champion, especially with his straight shots. Muhammad was answering and going toe-to-toe, but JDM seemed to remain in control. Muhammad looked to pick up the pace in round four, increasing the volume in his striking. JDM prevented another takedown, but Muhammad was able to get to his back. Muhammad, who appeared to be landing the stronger strikes in the round, pressed the action late with JDM against the fence.

JDM connected on a few solid straights early in the fifth round, busting open Muhammad. But Muhammad wobbled JDM with a straight of his own before scoring a takedown. JDM was able to work his way back up with about two minutes left. He started to connect more on Muhammad, and he appeared hurt. JDM went into a clinch, however, giving Muhammad another opportunity. Muhammad rolled through on a takedown attempt and got on top. Despite some difficulty, JDM was able to get back to his feet.

Jack Della Maddalena Upsets Belal Muhammad For UFC Welterweight Title At UFC 315

JDM originally came into the UFC through Dana White's Contender Series in 2021, and he's now 8-0 and a world champion in the Octagon. Della Maddalena, who hasn't lost since dropping his first two professional MMA fights, fought for the first time tonight since defeating Gilbert Burns in March 2024.

This loss snaps an 11-fight win streak Muhammad had been on since 2019. It was his first defense of the UFC welterweight championship since defeating Leon Edwards at UFC 304 back in July.
