The UFC is aware of Nick Diaz’s recent arrest and will conduct its own investigation into the allegations surrounding the onetime welterweight title challenger.

“The organization does not tolerate domestic violence and requires all athletes to adhere to the UFC Fighter Conduct Policy,” the promotion stated today in a press release hours after Diaz’s arrest on multiple charges of domestic violence. “Every athlete is deserving of due process and this situation, as with any official allegations, will be duly reviewed and thoroughly investigated by an independent party.”

Diaz remains in custody at the Clark County (Nev.) Detention Center in Las Vegas after he was arrested Thursday night. He is charged with one count of felony domestic battery by strangulation, as well as misdemeanor domestic battery. A source with knowledge of the case told MMAjunkie that 12 units were dispatched to a residence in Las Vegas after Diaz allegedly assaulted a female victim, who later was transported to a local hospital. The source said Diaz fought with the officers before being subdued.

Diaz has a court hearing scheduled for Saturday at 9 a.m. His bail currently is set at $18,000.

Contracted UFC fighters are held to the Fighter Conduct Policy, which subjects them to potential sanctions for bad behavior outside of the cage. The sanctions include: “penalties, payment deductions and/or reductions, suspension and termination of the independent contractor relationship, and may include conditions to be satisfied to continuing to contract with UFC.”

Diaz hasn’t fought since a 2015 decision loss to Anderson Silva, but remains under contract with the promotion. After a one-year sanction from USADA for failing to notify the UFC anti-doping partner of his whereabouts, he hinted at a return to the octagon.

The UFC specifically mentions domestic violence in its standards of conduct, stating “the use or threat of violence, domestic violence and other forms of partner abuse” is “clearly detrimental to the reputation of UFC and therefore subjects the athlete to sanctions.”

Although the promotional guidelines state that decisions are made on a case-by-case basis after independent review, it also states that an incident “involving significant harm or sexual misconduct,” even prior to the fighters contracted relationship with the UFC, “or previous violations of the UFC Promotional Guidelines may result in an immediate sanction.”

Diaz hasn’t been cited for any previous violations of the promotional guidelines, though he’s been suspended on three occasions by the Nevada State Athletic Commission for marijuana infractions in connection with his fights.
