Law enforcement is looking into a weekend attack on UFC fighter Rachael Ostovich.

The Honolulu Police Department has opened a second-degree assault investigation related to an incident that occurred early Sunday morning involving “a 27-year-old female victim and a 27-year-old male suspect,” spokesperson Sarah Yoro told MMA Fighting on Monday. Per Yoro, the suspect and victim were arguing prior to the alleged assault.

“The victim suffered head injuries and was treated at a hospital,” Yoro said.

The attack happened at 2 a.m. Sunday morning at a residence in the Waianae section of Honolulu County, Yoro said. No arrest has been made. Second-degree assault is a felony in Hawaii.

Honolulu PD does not release the names of those involved in alleged crimes. But sources told media that the female victim in question is Ostovich and the male suspect is allegedly her husband Arnold Berdon, who is also an MMA fighter.

Ostovich was taken to the hospital Sunday, treated for a broken orbital bone and later released, sources confirmed after reports from TMZ and ESPN.

Ostovich, a UFC flyweight and alum of The Ultimate Fighter 27, was scheduled to fight Paige VanZant on the UFC’s ESPN+ debut card Jan. 19 in Brooklyn. Sources said Ostovich (4-4) is out of that fight and the UFC is currently seeking a replacement to fight VanZant on the card. The UFC has yet to comment on the situation.

Berdon, a bantamweight fighter, last fought for Titan FC in June. He is 6-2 as a pro.

Update: Later Monday night, Ostovich’s Sucker Punch Entertainment management released a statement regarding the situation and confirming that Ostovich is out of the fight with VanZant.

“A very unfortunate incident occurred Sunday night with Rachael Ostovich that ended with her suffering a fractured orbital and other injuries,” the statement read. … “Rachael is now home from the hospital with family and will be going back for further check ups on her orbital. The family would like to ask for some privacy as they sort through this matter. We would like to thank the UFC for all their support on this matter as well as the fans and media for your concern.”
