TUF 17: Uriah Hall and the 5 Best KOs in the History of 'The Ultimate Fighter'

No knockout in the eight-year history of The Ultimate Fighter epitomized brutality, precision and showmanship quite like Uriah Hall’s spinning hook kick from hell in the show’s latest episode.

Team Sonnen’s Hall not only gracefully executed the low-percentage finishing technique, he also landed it flush on the jawline of Adam Cella, sending the Team Jones member into a frighteningly deep state of unconsciousness.

Although Cella eventually woke up and attempted to laugh off the incident, none of the remaining fighters in the house were chuckling at the grim prospect of locking horns with Hall.

Here’s a glance at the top five knockouts in The Ultimate Fighter history.

5. James Vick Accidentally Knocked out Daron Cruickshank

Vick’s knockout of Team Faber's Cruickshank on The Ultimate Fighter 15 was so polarizing because it essentially happened by mistake.

Cruickshank attempted to shoot a lazy double-leg takedown at the same time that the long and rangy Vick tried to zero in on his head with a high kick.

Rather than whipping the kick over his opponent's head, Team Cruz's Vick stopped his kicking motion and drove the crown of his knee into Cruickshank’s chin to score the highlight-reel knockout.

Cruickshank hit the mat violently and woke up minutes later wondering what had happened.

Needless to say, Cruickshank inked a multi-fight contract with the UFC in 2012, and Vick, who lost his semifinal-round bout on The Ultimate Fighter 15, hasn’t competed professionally since.

What’s the moral of the story? Don’t shoot a lazy double-leg on a 6’3” lightweight.

4. Ryan Bader Made His UFC Debut Count by Smashing Vinny Magalhães

Arguably the best jiu-jitsu practitioner to ever compete on The Ultimate Fighter, Magalhães never got a chance to try to outgrapple Bader, a former two-time NCAA All-American wrestler.

In the fight that jump-started his UFC career, Team Nogueira's Bader landed a hammer of an overhand right to Magalhães' temple, flooring the Team Mir member and opening the door for some fight-ending ground strikes just 2:18 into The Ultimate Fighter 8 Finale.

Magalhães instinctively rolled for a leglock, only to eat three vicious right hands and three hammerfists before referee Herb Dean saved him from further damage.

Magalhães has since competed in the UFC just once, while Bader has racked up a 7-3 record in the promotion since then.

3. Justin Lawrence Used Advice of Coach Dominick Cruz to KO Cristiano Marcello

Squaring off with Team Faber's best grappler, Marcello, in the first round of The Ultimate Fighter 15, Lawrence devised a game plan to pick apart the 35-year-old Brazilian from a distance.

Lawrence stalked Marcello for over five minutes until the 21-year-old recognized an opening to land a ferocious left hook.

With his coach, Cruz, demanding feints from Lawrence, the Black House MMA product obliged and reaped the benefits. Lawrence landed an inside leg kick, hopped forward with a feint, and then smoothly crushed Marcello's nose and upper lip with a violent left hook. When Marcello, a renowned jiu-jitsu coach, woke up, his dream of fighting in the UFC had vanished.

2. Matt Riddle Did a Number on Dan Simmler's Jaw

The aftermath of Riddle's victory over Simmler told the tale of just how ruthless this knockout was in The Ultimate Fighter 7.

The 22-year-old Riddle immediately rendered Simmler unconscious when he clipped the Matt Serra disciple on the button with a venomous right hook. For good measure, Team Rampage's Riddle then dropped three lethal hammerfists on Simmler's jaw before screeching like a barbarian in celebration.

Carted off on a stretcher and taken to the hospital by ambulance, Simmler broke his jaw in two places and suffered a concussion. Simmler has competed twice since the knockout, winning both of his bouts in the Cage Fighting Xtreme promotion.

1. Hall Did His Best Edson Barboza Impression on Cella's Face

When Hall detected a brief opening to throw the unorthodox kick, he knew precisely when to unload it.

Cella stopped moving his feet for a few seconds, and even though his hands were hovering near his chin, he stood directly in Hall's wheelhouse.

Hall activated his fast-twitch muscle fibers and whipped his heel around the back of Cella's right ear.

The Missouri native lost consciousness and began snoring before hitting the mat, sending a chill through Hall and prompting the Jamaican striker to issue an immediate apology.
