UFC International Fight Week returns to Las Vegas with UFC 303 on June 29, headlined by a blockbuster main event featuring the return of superstar Conor McGregor as he collides with Michael Chandler in a highly anticipated welterweight bout.
McGregor (22-6, fighting out of Dublin, Ireland) makes his long-awaited return to settle his rivalry against opposing The Ultimate Fighter season 31 coach Chandler. The Irishman aims to deliver another iconic moment against Chandler, kickstarting another run at UFC gold.

The first fighter in UFC history to hold two division titles simultaneously, McGregor has become a sports icon through his legendary performances against José Aldo, Eddie Alvarez and Donald Cerrone.
Chandler (23-8, fighting out of Deerfield Beach, Fla. by way of Nashville, Tenn.) finally gets his shot at the sport's biggest star. He now looks to secure the biggest win of his career by finishing McGregor in unforgettable fashion.
A fan favorite incapable of delivering a dull moment in the Octagon, Chandler has become a must-watch after his highlight-reel finishes against Dan Hooker and former interim UFC lightweight champion Tony Ferguson.
Also, former UFC light heavyweight champion and No. 3 ranked contender Jamahal Hill makes a quick return to take on rising No. 8 Khalil Rountree Jr. in a pivotal co-main event.
Former UFC light heavyweight champion Hill (12-2 1NC, fighting out of Grand Rapids, Mich.) returns to action with a vengeance. Hill plans on reminding the 205-pound division why he's one of the best in the world by delivering a statement performance against Rountree Jr.
The Michigan-native made a name for himself by delivering three straight knockouts against Jimmy Crute, Johnny Walker and Thiago Santos on his way to capturing the division's title from Glover Teixiera.
Rountree Jr. (14-5 1NC, fighting out of Las Vegas, Nev.) embarks on his first outing of the 2024 season. The rising contender looks to make it six in a row and inch his way closer to a title opportunity by silencing former division champion Hill.
An eight-year Octagon veteran, Rountree Jr. has become an unrelenting force and knockout machine, finishing the likes of Anthony Smith, Chris Daukaus and Paul Craig.
