As noted by MMA Fighting, Ulberg beat Alonzo Menifield quickly to pick up his sixth straight win and enter the record books.

With Ulberg making history at UFC Fight Night: Lewis vs Nascimento, Sports Brief looks at the fastest knockouts in the division.

5 fastest knockouts in Light Heavyweight division

Ryan Jimmo vs Anthony Perosh

In July 2012, Ryan Jimmo made his debut in the UFC, and it was a debut no one would forget.

The Canadian MMA fighter needed just seven seconds to knockout Australia’s Anthony Perosh, thanks to a vicious overhand right.

The quick victory is tied for the third-fastest in UFC history and the fastest in the Light Heavyweight division.

Jimmo’s quick win wasn’t the only thing that got people talking, so did his robot dance celebration afterwards.

James Irvin vs Houston Alexander

James Irvin wasted little time when he took on Houston Alexander at UFC Fight Night 13.

After just four seconds, the Sandman landed a brutal Superman punch that dropped the Assassin, and then it took him four more seconds to land some nasty shots on the ground.

The referee quickly intervened to prevent Alexander from taking more punishment. The Assassin disagreed with the decision, and some crowd members also booed, believing it was an early stoppage.

Carlos Ulberg vs Alonzo Menifield

Ulberg picked up his sixth straight win in the UFC when he stopped Menifield in fine fashion.

The Kiwi needed just 12 seconds to beat the American by TKO.

After the bout, Ulberg admitted that his opponent caught him with a shot early on, but the blow woke him up. He then went on the offensive and knocked out the American.

Anthony Johnson vs Glover Texeira

Johnson needed 13 seconds to beat Texeira when the duo faced off at UFC 202.

Johnson started with a few jabs, finding his range, before unleashing a right uppercut that knocked out the Brazilian.

It was the first time Texeira had been knocked out since his debut in 2002. Following his victory, the American set his sights on Daniel Cormier.

Anthony Perosh vs Vinny Magalhaes

Perosh may have been the victim of the fastest knockout in Light Heavyweight history, but he also delivered a quick finish of his own.

In 2013, Perosh rocked Magalhaes with a TKO victory in just 14 seconds.

The win came a year after he was knocked out in seven seconds.

Cejudo wants Adesanya vs Pereira 3

Sports Brief earlier reported Henry Cejudo wanted to see Israel Adesanya and Alex Pereira face off again.

The duo have battled each other twice in the UFC, with each picking up a victory over the other via KO/ TKO.

Pereira is now the Light Heavyweight champ, while Adesanya could win the Middleweight title again.
