“I went 80-percent,” Jones said about the Gustafsson fight. “I’m not making any excuses, Gustafsson did a great job in the fight, but I know I had a lot more in me. I did some of the cardio tests that I normally do and my numbers weren’t the same.

“Me knowing that, I still went into the fight thinking well since I can’t perform excellent, maybe I’ll still perform really, really high and still really, really good and maybe the fight will be a little bit closer if I just put half the effort in. I learned the lesson the hard way that you have to give full effort.”

In a recent interview with FOX Sports, UFC light-heavyweight champion, Jon ‘Bones’ Jones. admitted that he didn’t give his full effort in his last fight against Alexander Gustafsson.

The bout was a close decision, many thought Jones lost. Is this an excuse, or you think the champ is being honest?
