14. Johny Hendricks (12 secs) vs. Jon Fitch, UFC 141

With two straight wins under his belt, Hendricks was handed the biggest fight of his career in the UFC 141. 

His opponent Jon Fitch was also a long time contender with a lot more wins to his name. 

Fitch was tipped to prevail over Hendricks because of his successful run and track record in the Welterweight division.

Yet Hendricks’ powerful left knocked out Fitch in less than 12 seconds. 

Hendricks showed just the same hunger and desire to win in the next three fights that followed and became one of the top contenders in the division.

13. BJ Penn (11 secs) vs. Caol Uno, UFC 34

Penn knocked Uno out with an uppercut, then followed it up with several punches, and the fight was over, taking only 11 seconds. 

Certainly one of the fastest UFC knockouts in the history of the sport.

But the timekeeper showed 11 seconds. 

It was not until years later that UFC got to investigate the time and saw that Ludwig knocked out Goulet in six seconds, and the timekeeper took too long to stop the clock.

But the original ruling was not overturned, so the official records say 11 seconds; so 11 seconds it is.

11. Mark Weir (11 secs) vs. Eugene Jackson, UFC 38

When Mark Weir got picked for the UFC roster, he already had an impressive record (8-1).

His first UFC fight saw him go against Eugene Jackson, who was already a veteran.

Irvin didn’t relent and followed it with some more pound shots, and that did it.

Alexander was knocked out eight seconds into the fight, thus handling Irvin an impressive win.

Amirkhani was up against Ogle in his UFC debut, and hopes were high.

Although while hopes highs and anticipation in Amirkhani camp, it was a different mood entirely in Ogle camp.

Ogle was on a four-fight losing streak and thus was under immense pressure. 

This was more than just a fight to Ogle; this was a fight to keep his job.

He recorded the first twister submission in the UFC in his debut fight against Leonard Garcia and was bound to face Hominick in his next fight.

Hominick was also a heavy name too. As much as the odds seemed balanced, it still looked to favor Hominick; for one, he had never knocked out by strikes.

However, when the fight kicked off, all that changed. Hominick had charged in aggressively at the Korean Zombie. 

That move played a disadvantage to Hominick as it delivered him right into Jung’s hands. 

Jung wasn’t forgiving; he countered Hominick’s aggressive strikes that dropped Hominick down and followed it with punches. 

The result, as we all know it, Jung became the winner in just seven seconds.

3. Ryan Jimmo (7 secs) vs. Anthony Perosh, UFC 149

When Jimmo penned a contract deal with UFC in 2012, he was one of the promising fighters on the regional scene. 

He had triumphed over big names, the likes of Marvin Eastman, Rameau Thierry Sokoudjou, and Wilson Gouveia. 

Despite his achievements, there was not much excitement ringing with his name in the MMA fighting scene. 

An unspoken belittlement was associated with Jimmo majorly for the fact that most of his wins in his career up until that point in time were decisions from judges’ scorecards. 

But his UFC debut fight at the Scotiabank venue in Calgary, Alberta, Canada changed the story.

Jimmo knocked out veteran fighter, Perosh in the most spectacular way you’d imagine in just 7 seconds to mark a memorable debut into UFC.

However, after his debut fights, the roof of anticipation was on fire. 

Duffee was a respected fighter and feared, and the facts he was facing Tim Hague, another equally respected and feared; fighter, seemed to everyone in a sense that the bully had finally met his match. 

However, after the fight, the story took an utterly different twist.

It so happens that Duffee, on the contrary, had rather met another victim of his blows in the octagon than a rival. 

He dropped Hague in an instant with a stiff jab just seven seconds into the fight to emerge the winner.
