The UFC 243 PPV main card is in progress, and the unranked Sergey Spivac just choked out the promotion’s #14 ranked heavyweight Tai Tuivasa. Spivac hit several takedowns before cinching up an arm triangle in the second act. This was definitely the biggest win of the Ukrainian’s career. Before that, Dhiego Lima used his devastating leg kicks to stay ahead of Luke Jumeau and take a split decision. The match seemed to be all in Lima’s favor, rendering the split result a bit of a mystery. Don’t look now, but Lima is on a three fight winning streak. Opening up the PPV main card, Yorgan De Castro scored a massive walk-off knockout of Justin Tafa inside of the first round.
