• Marcin Prachnio knocked his opponent out with a debilitating kick to the body.

• The finishing move was so awesome the UFC awarded Prachnio with a cash bonus.

A UFC striker called Marcin Prachnio scored a second-round finish to remember Saturday when he lashed his opponent's body with a crippling kick at a behind-closed-doors MMA event in Las Vegas.

The video clip below is a brutal reminder that knockouts to the body can sometimes be more painful than those to the head, as the opponent - Ike Villanueva - writhed around in agony on the canvas.

Villanueva connected with 49 of his 80 strikes (61% accurate) and also succeeded with a takedown attempt in the opening round. Prachnio said after the match that he felt Villanueva was getting the better of him.

And so, the 32-year-old entered the second round determined to close the show. "The plan in the second round was to win the fight," Prachnio said in a statement sent to Insider.

"I had in my head the idea of finishing him on the second round and that's what happened. I just worked for it and kept in mind winning the second round.

"The first round was tough. I got my two eyebrows open. I couldn't see from my left eye for half the round, but then after the break, I was fine again."

Prachnio said he could tell through the fight that Villanueva was "struggling with taking those low kicks." His team had said pre-fight that he might be tough to knockout with headshots, so they focused more on striking lower.

"In the second round, I hit two liver kicks and it worked," he said.

Watch it right here:

The victory advanced Prachnio's pro-MMA record to 15 wins (11 knockouts against one submission and three decisions) against five losses.

Prachnio's kick was deemed so awesome that the UFC boss Dana White awarded the fighter a $50,000 performance-related bonus.

Finishing, Prachnio said: "After a few rough years in the UFC, I just got in a good winning streak, two wins, and I'm just going to keep it like that, keep winning.

"I think the bad times are behind me already and now it's going to be my time to shine."
