UFC Fight Night: Lewis vs. Olenik Highlights: Derrick Lewis Sets Heavyweight KO Record Against Aleksei Olenik

Derrick Lewis shut off Aleksei Olenik en route to securing the UFC heavyweight record for most knockouts at UFC Fight Night: Lewis vs. Olenik.

Lewis has broken away from the pack, separating from Cain Velasquez and Junior dos Santos en route to setting a new heavyweight KO record. He did so with a flying knee to the chest followed by a winging right hand that dropped Olenik. "The Black Beast" smothered his opponent on the ground, separating Olenik from conciousness with vicous ground-and-pound strikes.

The finish came officially at 0:21 of round two. Lewis improved his professional record to 24-7-0-1 and now rides a three-fight winning streak with Ws over Olenik, Ilir Latifi and Blagoy Ivanov. In typical Lewis fashion, he kicked off his post-fight interview with Paul Felder by proclaiming, "I need to take a s--t."

UFC Fight Night: Lewis vs. Olenik takes place at the UFC Apex in Las Vegas, Nevada. Keep up with Fightful right here and on Twitter for live highlights, recaps and post-fight coverage from Saturday's event.
