The UFC heavyweight division is fast becoming one of the promotion’s most intriguing.

Derrick Lewis helped with that on Saturday night when he knocked out top contender Curtis Blaydes in devastating fashion and shook up the title picture in the process.

Down a round, Lewis was waiting for Blaydes to launch head-first into a takedown early in the second stanza. Little over a minute into that second round, Blaydes paid the price for his takedown attempt as his jaw met Lewis’ uppercut, rendering him unconscious immediately.

Lewis then delivered two brutal ground and pound punches on the downed Blaydes to secure one of the biggest wins of his career.

Here is how their fellow fighters reacted to Lewis’ victory as well as the rest of the fights on that UFC Vegas 19 card.
