Roy Nelson‘s frustration over what he deemed a late stoppage in his recent fight with Antonio “Bigfoot” Silva has landed him in hot water. The UFC heavyweight is now facing a lengthy suspension and significant fines.

Nelson landed a right uppercut that dropped Silva late in the second round of their UFC Fight Night Brasilia main card bout on Sept. 24. Silva crashed to the canvas and Nelson reluctantly delivered a few more shots before referee “Big” John McCarthy stepped in to stop the action. Nelson felt it was a late stoppage.

Nelson and Silva have a close relationship. After the fight, Nelson kicked or pushed McCarthy in the buttocks out of frustration. He then flipped McCarthy off, while hurling obscenities at the veteran referee.

“I didn’t want to hurt Bigfoot more than what I had to. I got taken from the moment. I apologized to Big John, but I wouldn’t take it back,” Nelson said after the fight. “It just hurt me that I’ve got to keep on hitting a guy that doesn’t need to be hit. The referee just did a late stoppage.”

While Nelson apologized, UFC president Dana White blasted him for his actions during an episode of the UFC Unfiltered podcast.

“You can’t apologize for that. You don’t ever, ever put your (expletive) hands on a referee or your feet for any reason what-so-(expletive)-ever,” said White. “You don’t do it. He needs to be buried.”

Addressing the issue, the Brazilian Athletic Commission on MMA (CABMMA) turned adjudication of the incident over to the Superior Justice Court of Sport, the governing body of sports in Brazil.

Now in the hands of the Superior Justice Court of MMA (STJDMMA), according to a Thursday report by MMAFighting.com's Guilherme Cruz, Nelson has been issued a 90-day temporary suspension, pending the adjudication of his case.

According to STJDMMA documents sent to MMAFighting, Nelson could be charged with assaulting McCarthy, which is accompanied by a fine of up to $30,000 and a six-month to two-year suspension. He could also be charged with unethical behavior, which comes with a fine of up to $10,000 and a 30-day to six-month suspension.

The document indicated that the Superior Justice Court attorney who filed the complaint suggested a 14-month suspension and $18,500 fine. Nelson has seven business days to respond and present a defense.

It is apparently up to the president of the STJDMMA to evaluate and rule on the case.
