An unbeaten MMA fighter hit his UFC 267 opponent with a devastating knee, then asked Dana White for a bonus

• Lerone Murphy just added another thunderous knockout to his highlight-reel.
• The British UFC fighter destroyed Makwan Amirkhani with a knee strike in the second round.

ABU DHABI - British MMA fighter Lerone Murphy's star shines even brighter after his thunderous knockout via knee strike Saturday at the UFC 267 event Insider attended inside the Etihad Arena in Abu Dhabi, United Arab Emirates.

Competing against Makwan Amirkhani in a featherweight fight, Murphy had to come from behind to scoop the victory.

Amirkhani, an Iran-born Finnish fighter, took the fight to the ground in the opening minute of the first round, and asserted his authority with a superior grappling skillset.

Murphy managed to get to his feet, but was seemingly unable to shake Amirkhani's grip as they wrestled against the fence.

Amirkhani landed five of six takedowns in total in the first, and won a 10-9 round on all three of the judges scorecards, according to information seen by Insider.

Having been taken down so many times in the opener, and trailing on the cards, Murphy entered the second in no mood to fight on the mat.

And so shortly after the second round began, when Amirkhani shot for another takedown, Murphy timed a knee strike and landed the shot on his opponent's skull.

It was a screamer of a shot and put Amirkhani out cold unconscious for an uncomfortable amount of time.

Watch it right here:

As Murphy celebrated the victory, Amirkhani appeared motionless on the canvas.

After receiving medical treatment, Amirkhani eventually sat up, and received a cheer from the crowd for the effort.

Murphy then got on the microphone and implored the UFC boss Dana White to award him with a performance-related bonus check of $50,000.

Murphy joins numerous other British fighters who continue to make waves in the UFC, with Paddy Pimblett, Jack Shore, and Tom Aspinall all enjoying big wins throughout the year.

Victory preserved his unbeaten streak and advanced his pro MMA record to 11 wins (seven knockouts and four decisions).
