A variety of main UFC events are set to headline Madison Square Garden. The article lists both prior and upcoming headliners such as Conor McGregor, Georges St-Pierre, Daniel Cormier, Jon Jones, and Stipe Miocic. These fighters, who are known as some of the best in the sport, were expected to be part of a major heavyweight championship match until Jones suffered a pectoral tendon injury. After surgery, he and Miocic were forced off the card, leading to the introduction of substitute fighters Sergei Pavlovich and Tom Aspinall for an interim heavyweight championship. Furthermore, the vacated lightweight title fight between Jiri Procházka and Alex Pereira now takes the main event slot.

Despite the shifting line-up, UFC has attempted to maintain excitement for Saturday’s competition by highlighting the knockout power of fighters such as Procházka and Aspinall. Pereira, a former champion, looks to reclaim his title. With the absence of the original main event, attention has shifted to these new match-ups, while efforts are underway to reschedule Jones and Miocic’s match for a future event.

The article discusses upcoming fights between Procházka vs. Pereira and Pavlovich vs. Aspinall. Both contests involve fighters seeking to further establish themselves in the division. Procházka, a former champion, is looking to build on his successful UFC run. Pavlovich and Aspinall, relative newcomers to the UFC, will compete in a high-stakes battle at Madison Square Garden. The article also mentions betting odds and additional details about the fighters involved.
