Jon Jones' image, let alone fighting career, suffered greatly in 2015 due to some poor choices.

With the one-time Ultimate Fighting Championship (UFC) light heavyweight titleholder making a triumphant return to the organization, after being reinstated yesterday (Fri. Oct. 23, 2015), it appears not everyone is calling this a "good day" for the sport of mixed martial arts (MMA).

Just ask former "Bones'" foe Quinton "Rampage" Jackson, who claims it's not just the actions of the former pound-for-pound star outside the cage that deserve attention (via Inside MMA).

"I hope he comes back. I hope he learns from his mistake.... But I'm not saying it because I'm a fan of Jon Jones because honestly I think that Jon Jones is bad for the sport, because when he fights people, he injures us. He kicked my knee backwards, my knee is never the same. He's done it to a couple other guys. I saw him rip one guy's shoulder out his socket. We just try to the same thing he's trying to do, earn a living and do the sport that we love. We don't go in there to try and injure people, even though I tried to fold an opponent in half, but he made me angry, it was something that he did to me, I had a history.... But this guy's doing it to every opponent. He's kicking their knees backwards and really trying to hurt people. So I think that's bad for the sport."

Jones and Rampage previously fought in Sept. 2011 at the UFC 135 pay-per-view (PPV) in what was the former's first 205-pound title defense. The Albuquerque, N.M.-based fighter would submit Rampage via rear-naked choke in the fourth round, but it wasn't the finish that had the latter fuming roughly 17 months later.

One of the unorthodox striking techniques Jones employs are a bevvy of low, or side, kicks that attack the knee, which lead the former light heavyweight champion to call him "dirty."

Of course, this isn't anything new for Jones, whose garnered attention multiple times for questionable Octagon strategies. Whether he stops is up to him, and the opponent.

For Jones, that may come sooner rather than later. Mr. "DC" is waiting.
