Nate Diaz has been charged with misdemeanor battery stemming from an alleged incident at a nightclub in Las Vegas back in August.

According to online court records obtained by MMA Fighting, Diaz was hit with the misdemeanor battery charge on Oct. 16 over an incident that allegedly took place on Aug. 24 at the Omnia nightclub in Las Vegas. TMZ first reported the news.

Diaz’s representatives did not respond for comment from MMA Fighting.

The charge stems from an alleged altercation at the club where Diaz and some friends were waiting in line to be admitted into the Omnia nightclub inside Caesar’s Palace.

Diaz and his friends were reportedly holding up the line when a security guard from the Omnia approached the ex-UFC fighter to see what was happening. The situation turned physical after Diaz allegedly pushed the security guard, who then pushed him back before Diaz allegedly hit the security guard in the face with “an open right hand.”

A video of the alleged altercation circulated back in September that shows Diaz shoving a person away by the face, knocking off their glasses before putting up his hands with more people swooping in to de-escalate the situation.

By the time police arrived to deal with the altercation, Diaz had already exited the property.

A misdemeanor battery charge was eventually filed against Diaz in October and the case is ongoing.

If convicted, Diaz faces a potential penalty of up to six months in jail and fines up to $1,000 but it’s highly unlikely he’ll deal with the maximum penalty in a misdemeanor case like this.

The 39-year-old fighter was actually just in Las Vegas this past weekend cornering his friend Kron Gracie at UFC 310 for his fight against Bryce Mitchell. Diaz last appeared in the ring back in July when he won a decision in a boxing match against fellow UFC veteran Jorge Masvidal.
