Who won the UFC 229 main event against Conor McGregor in 2018?

Khabib Nurmagomedov won the UFC 229 main event against Conor McGregor in 2018.

Nurmagomedov defeated McGregor by fourth-round submission on October 6, 2018, at T-Mobile Arena in Las Vegas. He secured a neck crank after controlling McGregor on the ground, retaining the UFC lightweight championship in the process.

The bout was one of the most heavily promoted fights in UFC history because of the fighters’ long-running personal rivalry and the events surrounding McGregor’s attack on a bus carrying UFC athletes earlier in 2018. The post-fight scene included a major brawl, leading to disciplinary action. Despite the controversy, the official result remains Nurmagomedov’s submission victory and his undefeated professional record at that time.
