MMA fighter Tara LaRosa showcased her octagon skills in Oregon over the weekend, restraining an anti-President Trump protester during a flag demonstration ahead of Veterans Day.

LaRosa, 41, was among a group of people waving US flags in northeast Portland on Sunday when a confrontation between her and a woman who was scuffling with right-wing protesters broke out, The Oregonian reports.

Footage of the dustup retweeted by LaRosa shows the MMA legend atop a woman who identified herself as a professor and repeatedly said that she couldn’t breathe as the mixed martial artist pressed down on her.

“Call the cops,” LaRosa said. “Stop, stop, stop – relax.”

The woman beneath LaRosa denied that she assaulted anyone while another man can be heard yelling in the background: “How do you like the Proud Boys now?”

LaRosa accused the unidentified woman of provoking the flag-waving demonstrators, video shows.

“You’re antagonizing the city I live in,” she told LaRosa. “Just let me breathe.”

“No, we’re not, we’re doing a flag wave,” LaRosa replied. “We’re not trying to fight.”

The woman allegedly bit LaRosa through her shirt and bra during the melee, leaving bite marks near her breast. LaRosa also had scrapes to her neck and knees, according to photos posted on Twitter.

No arrests were made, but the case has been referred to the Multnomah County District Attorney’s Office, The Oregonian reports.

“There are conflicting versions of the events, so we are gathering all of the information we can and referring it to the district attorney,” Portland police Sgt. Kevin Allen told the newspaper in a statement.
