Main event fighter out of Noche UFC, replacement named

Yair Rodriguez is out of the Noche UFC 4 main event.

Rodriguez was scheduled to face Jean Silva on the Sept. 12 event in Glendale, Arizona but undisclosed reason forced him to withdraw. Instead, Silva will take on Arizona native Jose Delgado in a  five-round fight.

MMAFighting first reported the news and Silva and Delgado later confirmed it via social media. Rodriguez last competed in April 2025 and has been largely inactive in recent years.

Delgado (12-2) made his way to the UFC roster through the Dana White’s Contender Series in 2024. He’s won four of his five octagon appearances, is ranked No. 14 and is riding a two-fight winning streak. It’ll be his first UFC main event match.

Silva (17-3) has won 14 of his last 15 fights. He’ll enter UFC Noche 4 ranked No. 6 in the 145-pound weight class and coming off a decision win over Arnold Allen in his last outing.

The event, which takes place at Desert Diamond Arena, is expected to feature 13 bouts. The event will mark the promotion’s third visit to Glendale and will be the fourth annual Noche UFC event commemorating Mexico’s independence day.
