There were many exciting moments at UFC 158.
One of the most exciting came when Jake Ellenberger knocked out former Strikeforce welterweight champion Nate Marquardt in the first round of their fight.
Although it appeared Marquardt was ready to make a triumphant return to the Octagon, Ellenberger spoiled the party.
Although it was a short fight, here is a technical breakdown of it.
The first thing of note was Jake Ellenberger coming out to Coolio's most famous song, Gangsta's Paradise. Perhaps the dark song set the mood for what Ellenberger was going to do to Marquardt.
As the round began, Marquardt looked like a whole weight class bigger than Ellenberger. Ellenberger is a strong welterweight, though.
Marquardt took a page out of Tarec Saffiedine's book as he was looking to land a lot of leg kicks.
Although Ellenberger was landing some shots, one of which cut Marquardt, nothing was really significant.
Both men clinched at the fence, but broke it up and got back to the center of the Octagon.
After a little bit of exchanging, Ellenberger caught Marquardt with a left hook then dropped him with a right.
Ellenberger put the finishing touches on Marquardt and earned a knockout victory.
Marquardt tried to protest what happened but he was clearly out of it.
That's all she wrote as Ellenberger earned his 18th knockout victory.
