The biggest fight in the combat history of Australia and New Zealand went down inside the Marvel Stadium in Melbourne, Australia.
The co-main event saw Al Iaquinta take on Dan Hooker in an important Lightweight contest. Tai Tuivasa and Sergey Spivak were involved in a heavyweight scrap while former TUF competitor Dhiego Lima looked to extend his win-streak.

UFC 243 Results: Main Card
#1 Yorgan De Castro (5-0) vs. Justin Tafa (3-0) (Heavyweight)
The main card kicked off with a heavyweight bout between two undefeated fighters. It doesn't get any better than that!
Round 1: They engaged from the get-go and threw bombs at each other near the fence. Both men settled for a body lock with Tafa pushing Castro against the cage.
Tafa landed a few punches to the body in the lockup. Tafa continued to work the body with punches and landed a few uppercuts on the break and both were back circling in the centre.
Tafa squared up and came in for a big overhand right, however, Castro timed his power right to perfection, that landed straight to Tafa's jaw and it was lights out. Castro walked away in classic Mark Hunt style to make the knockout look even more special. Now that's how to kick off the main card!
Result: Yorgan De Castro def. Justin Tafa via KO (2:10, Round 1)
Yorgan De Castro couldn't have asked for a better debut. A quintessential one-punch walkout doesn't happen quite often, but when it does, it's a proper highlight-reel moment and The Mad Titan deserves all the props.
Justin Tafa's undefeated streak ended with one of the best knockouts of the year.
