UFC Light Heavyweight Champion Jon Jones and top contender Daniel Cormier both stood before the Nevada State Athletic Commission today, in a hearing regarding their brawl at a press event last month.

Both Jones and Cormier were fined and sentenced to community service for their part in the melee. Jones, noted as the aggressor in the event — a scheduled stare-down before media, which was interrupted by the two shoving, tackling, and punching one another — was fined $50,000, which will go to the NSAC general fund, and will also offer 40 hours of his time with at-risk children and anti-bullying programs. Cormier was fined $9,000 and will participate in 20 hours of service.

The fines each represent 10% of each fighter’s guaranteed purse for their fight, which was originally scheduled for this weekend in Las Vegas. Their bout was postponed due to an injury suffered by Jones.

Jones noted he had already lost a sponsorship deal with Nike, said to be “six figures” in value, as a result of his actions.

Cormier, whose hearing was held after Jones, described losing several key members of his youth wrestling program as a result of the brawl, including an All-American.

The two will face one another in the Octagon on January 3 in Las Vegas, at UFC 182. This weekend’s UFC 178 is headlined instead by a flyweight title bout between champion Demetrious Johnson and challenger Chris Cariaso.

Also today, the NSAC levied a $70,000 fine to Wanderlei Silva, who announced his retirement from the sport last week. Silva is suspended indefinitely from MMA competition.

Silva had ducked away from a random drug test in May. He did not appear at today’s hearings.
