Round 1 was mostly Evans wearing down Salmon with wrestling and clinches. It was during round 2 that Evans landed his legendary head-kick, knocking Sean unconscious instantaneously. 

This vicious knockout propelled Evans into UFC superstardom and later on, becoming the UFC Light Heavyweight Champion.

The first round was savage, with Couture raining blows on Lidell’s temple and Lidell’s thumb plunging into Couture’s eye. 

However, ‘savage’ took on a whole new meaning when Lidell punched Couture’s chin and knocked him unconscious. This victory was significant for Lidell because he reclaimed the light-heavyweight champion title that he had lost to Couture two years ago.

Dan Henderson earned the name ‘Dangerous Dan’ for very strong reasons, one of which is his UFC 100 performance against Michael Bisping.

Henderson and Bisping had unsettled beef from The Ultimate Fighter reality show where they had been rival coaches, resulting in much trash talk from Bisping’s end in the buildup.

However, all went in vain during the second round when Henderson landed a perfect hit on Bisping’s chin with all the strength in this right hand. Yet another punch followed on the already KO’d Bisping, earning Henderson’s knockout ‘Knockout of the Night’ and several Knockout of the Year titles.  

Jorge Masvidal vs Ben Askren

The second the fight started, veteran welterweight Masvidal charged at a bent-over Askren, who attempted to duck a high kick but instead, received it flat on the ear and dropped unconscious

But Masvidal hadn’t had enough, courtesy Ben’s nasty trash talk preceding the fight. Masvidal rained down a couple more punches before the referee intervened, making it the biggest victory of his career.

The match began with veteran Menne aiming ineffective jabs and then an inside leg kick. The kick was when Baroni aimed a solid punch at Menne’s temple. 

It was a cakewalk for Baroni thereafter as he landed blow upon blow on a struggling Menne and in just over 18 seconds, Menne had been knocked out cold. What makes the victorious moment yet more remarkable is when Baroni straddled the cage afterward, screaming ‘I am the best ever!’

Scott Smith vs Pete Sell

This fight was one of the most shocking comebacks in UFC history, and everything about it was like something out of a movie. Scott Smith and Pete Sell, both equally skilled and powerful, were facing off when Sell aimed a hook at Smith’s left torso.

This seriously hurt Smith and threw him off balance and seemingly unable to put up a fight.

Smith’s iconic comeback was in Round 2 when he landed an effective punch on Sell’s face, knocking him out. Following this, Smith himself collapsed in pain from Sell’s previous blow.
