UFC 159 results: Roy Nelson knocks out Cheick Kongo
For Roy Nelson, it's feast or famine. He either scores the knockout shot or loses a decision, as evidenced by his recent record.
His last nine wins are by knockout. His last five losses have all gone to a decision.
Cheick Kongo is unlucky No. 10. Nelson caught the French fighter with a crushing overhand right, and finished him off with a single ground strike to win a UFC 159 main card bout. The stoppage came at 2:03 of the first round.
"All I do is set them up and knock them down," he said. "I want that gold."
Nelson (19-7) won his third straight, following wins over Matt Mitrione and Dave Herman.
Kongo never got his offense going. Earlier in the round, Nelson backed him against the cage where they clinched until being broken apart by the ref. It was only a few seconds later when Nelson dropped the hammer.
Kongo lost for the second time in three fights. He's now 18-8-2.
