But now he's no longer just an exciting name on the card. Now he's a legitimate title contender.
Jung scored the biggest victory of his career on Tuesday night, finishing young hotshot Dustin Poirier in a tremendous main event to UFC on Fuel TV 3. Jung used a D'Arce choke to win the bout at 1:07 of the fourth round.
Jung set the tone in the opening round, scoring a takedown and then delivering punishment from the mount. An elbow opened a cut on Poirier's head. Poirier had his moments, but Jung clearly won the round.
The second round was a memorable five-minute blur of action. Jung dropped Poirier (12-2) with a big knee, then put on a ground clinic, transitioning from an armbar to a triangle to another armbar to yet another triangle. Jung sunk in yet another triangle in the round's closing moments, but Poirier was saved by the bell.
Poirier had his best performance in round three. Jung was tired and dropped his hands. Poirier found his range with his left hand. But he never quite seized on the opening.
The end came early in round four, as the "Zombie" hit an uppercut and followed it with a knee. The fight went to the ground, where Jung cinched in the winning choke.
"He had me in trouble there at the beginning of the third round, the thought of giving up was in my head," Jung said through an interpreter. "But I just kept going and I got the win."
The win seems to put Jung next in line in the featherweight division, waiting for the winner of July's bout between champion Jose Aldo Jr. and Eric Koch. Jung left no doubt what he wants for his next fight, giving his response in English: "I want Jose Aldo."
