Marquardt, who lost a split decision at the event Saturday in London, probably would have won had he not committed two fouls. The judges scored the fight 28-27 for Leites, 28-27 for Marquardt, and 28-27 for Leites.
"On the first knee, I really thought he was getting up, and so it was definitely my mistake," Marquardt said. "On the second point the deduction, the elbow, I'm pretty sure it hit the side of his head, kinda towards his temple area, and it was a horizontal elbow, it should have been completely legal.
"I'm disappointed. I went out and fought my best, and really at this point, I'd really like a rematch, and I think we can settle it that way."
While Marquardt may have been wrongfully penalized for the second deduction, he was given a free pass for a piledriver in the closing seconds of the bout. Rules specifically forbid "spiking an opponent to the canvas on his or her head or neck."
The loss dropped Marquardt's record to 26-8-2. His only previous loss in the UFC was to middleweight champion Anderson Silva.
