UFC light heavyweight champion Jon Jones showed what he refers to as his “warrior spirit” Saturday night at UFC 165.

After taking the best Alexander Gustafsson had to offer – and maybe even a little more – Jones pulled out a decision victory inside the Air Canada Centre.

With the win, “Bones” earned his sixth successful title defense – a new record in the UFC for the 205-pound division. He also joined Royce Gracie, Georges St-Pierre and Anderson Silva as the only fighters in the promotion to win 10 consecutive bouts.

“I got to (show) my warrior spirit and that makes me happier than getting the win,” Jones said. “By far, this was my toughest fight. I proved a lot to myself, but I am not satisfied.

“I have to do a a lot more work in the gym to stay on top of my game.”

Jones was taken down for the first time in his UFC career by Gustafsson, and was denied on several takedown attempts. In the latter stages of the fight, though, it was Jones who seemed to turn it on.

Using elbows, spinning attacks and inside leg kicks, Jones did enough on the scorecards to earn the decision.

“I had some desperation (in the latter rounds),” Jones said. “I tried to stay calm and focused.

“Alexander was very game; he has a chin on him.”
