UFC fighter Nate Diaz hasn’t officially fought since his rematch with Conor McGregor at UFC 202 in 2016, but unofficially he just got into his second fight in as many months.

According to TMZ, Diaz got involved in a skirmish in the stands at the Fight to Win Pro 77 grappling event in Sacramento, Calif. on Friday night. The 33-year-old, who was there supporting some of his MMA students competing in the event, was reportedly witnessed throwing punches along with several other attendees of the event as they were being separated. He was not tossed out and no arrests were made, however.

It’s the second time this year that Diaz has found himself mixing it up at an MMA event in Sacramento. On May 11, Diaz allegedly got into a brawl with UFC fighter Clay Guida at a Combate Americas event.  The Sacramento County Sheriff’s Department reportedly investigated the incident but no charges were filed.

The last time Diaz actually took part in a sanctioned fight was his rematch with Conor McGregor nearly two years ago.  After winning a second-round submission over McGregor at UFC 196, he then lost a majority decision in the rematch at UFC 202, which set a record for the most purchased pay-per-view event in UFC history at an estimated 1.65 million buys.
