Dana White -- Conor McGregor-Michael Chandler UFC 303 fight off - ESPN

Conor McGregor will no longer fight Michael Chandler at UFC 303 on June 29 in Las Vegas, UFC president Dana White said Thursday night.

McGregor (22-6) was scheduled to headline the event but has withdrawn because of injury. It's the first time in McGregor's storied UFC career he's pulled out of a fight for any reason.

The new main event is a light heavyweight title fight between Alex Pereira and Jiří Procházka, according to White.

White also announced two more new fights to the card: Diego Lopes will face Brian Ortega in the co-main event and Carlos Ulberg will now fight Anthony Smith in a light heavyweight bout after Jamahal Hill, who was slated to fight in the co-main event, is out due to injury.

According to White, the sellout event was on pace to set a record for the UFC, with a live gate of more than $20 million. The UFC has not announced whether the nontitle welterweight bout between McGregor and Chandler will be rescheduled.

McGregor, 35, was set to return to competition for the first time since he suffered a broken leg in a TKO loss to Dustin Poirier in July 2021. The former featherweight and lightweight champion has only fought four times since a blockbuster boxing match against Floyd Mayweather Jr. in 2017.

McGregor is 1-3 in those appearances, with two losses to Poirier and a submission defeat to Khabib Nurmagomedov in a 2018 title fight.

The June fight being called off is a disappointing chapter in what's become something of a saga between McGregor and Chandler. Chandler, a former champion in Bellator MMA, first called out McGregor in earnest in 2022. The UFC announced the two would coach against each other on «The Ultimate Fighter» reality series in early 2023, which went ahead as scheduled that spring. A
