Jorge Masvidal was practising 48 hours before he delivered the flushest flying knee in UFC history.
Masvidal's head coach Mike Brown released footage of the drill on social media and it shows the exact same motion that knocked out Ben Askren at UFC 239.
You know what they say; practice makes perfect.
Masvidal's stunning flying knee was the fastest knockout in UFC history at just five seconds.
'Gamebred' followed up with two punches to the face before referee Jason Herzog stopped the fight.
The 34-year-old rubbed salt in the wounds as he celebrated by mocking Askren while he was receiving medical attention at the T-Mobile Arena, Las Vegas.
Following the bout, Masvidal didn't mince his words in a feisty post match press conference:
"I really wanted to beat his a** for 14 minutes and 50 seconds, but it didn't happen," he said.
"You should've kept your mouth shut, I probably would have beat you in the second round."
He then wished the "referee tripped on the way to breaking it up because I felt he deserved one more punch."
Askren posted on Twitter shortly after the fight, saying: "Well that sucked"
Masvidal will now have his eyes set on Kamaru Usman and his UFC welterweight championship.
Do you think he would beat Usman?
