Lewis stops Daukaus to break record for most KOs in UFC history

Derrick Lewis is the knockout king.

Lewis knocked out Chris Daukaus at the 3:36 mark in the first round of Saturday's UFC Fight Night heavyweight main event in Las Vegas.

"The Black Beast" now holds the most knockouts in UFC history with 13.

Lewis rocked Daukaus with a right hand and then put him down with uppercuts in the clinch.

The 36-year-old returned to the win column after suffering a TKO loss to Ciryl Gane in an August interim title fight. Lewis is now 5-1 in his past six Octagon appearances.

Daukaus suffered his first loss in the promotion, dropping to 4-1 and ending his five-fight winning streak. He had won all of his UFC bouts by knockout.
