Luke Rockhold says he was 'pissed off' after UFC 199 because Michael Bisping was 'classless'

Luke Rockhold wasn't upset at the UFC 199 post-fight press conference just because he lost. The former UFC middleweight champion said on social media Tuesday that he was miffed by Michael Bisping's actions in the Octagon after the bout concluded.

"After our first fight I picked him up off the canvas and gave him his due respect," Rockhold said in an Instagram post. "Bisping went out of his way to come across the cage not to shake my hand like a man but to further mock the situation. I felt it was a classless move on his part. Thus the reason I was so pissed off at the press conference. I don't believe in kicking a man while he's down."

I love the fight game and all that it offers. It's a chaotic world we live in but the reward far outweighs risk. Allowing the pressure of the situation get to me, I felt the need to preform and make a statement as opposed to staying calculated and winning the fight. I underestimated my opponent and paid for it. Forcing a fight that was unlike me, which left the door open. Credit to Micheal for being the tough guy that he is and capitalizing on the situation. Verbal warfare and fight hype is one thing, but that moment following the outcome of a fight is where a man's true character shines. After our first fight I picked him up off the canvas and gave him his due respect. Bisping went out of his way to come across the cage not to shake my hand like a man but to further mock the situation. I felt it was a classless move on his part. Thus the reason I was so pissed off at the press conference. I don't believe in kicking a man while he's down. I've been here before and I've always learned and grew from these situations. This will be no different. I will go home, heal up, and come back better than ever before. Bisping, I will see you real soon and I will finish this.

Bisping knocked out Rockhold in the first round Saturday night in the main event of UFC 199 in Inglewood, Calif. Bisping became the UFC's first English champion and did so as a huge underdog on just two weeks notice. Rockhold won the title from Chris Weidman back in December and this was his first title defense.

In the Instagram post, Rockhold made it very clear that he's thinking about an immediate rematch with Bisping. Both men still harbored hard feelings about the other after UFC 199. Those feelings stem from the lead-up to their first fight in November 2014, which Rockhold won by second-round submission.

"I've been here before and I've always learned and grew from these situations," Rockhold wrote. "This will be no different. I will go home, heal up, and come back better than ever before. Bisping, I will see you real soon and I will finish this."

Rockhold also mentioned before UFC 199 that he was dealing with an injured knee. He also stated repeatedly that he said he needed to finish Bisping in spectacular fashion. Rockhold said Tuesday that contributed to the stunning knockout Saturday night.

"I love the fight game and all that it offers," Rockhold said. "It's a chaotic world we live in but the reward far outweighs risk. Allowing the pressure of the situation get to me, I felt the need to preform [sic] and make a statement as opposed to staying calculated and winning the fight. I underestimated my opponent and paid for it. Forcing a fight that was unlike me, which left the door open. Credit to Micheal [sic] for being the tough guy that he is and capitalizing on the situation."
