ALBANY — New York is a gubernatorial signature away from becoming the last state in the US to legalize professional mixed martial arts.

Three Assembly committees cleared the way Tuesday for the combat sport to be approved by the full Assembly, which did so in a 113 to 25 vote after a debate that lasted more than three hours.

“Two nearly naked hot men rolling around on top of each other, trying to dominate each other: In case you didn’t know, that’s gay porn with a different ending,” joked Assemblyman Daniel O’Donnell (D-Manhattan), who is openly gay and opposed to what he called “an alleged sport.”

But Assemblywoman Rodneyse Bichotte (D-Brooklyn), said she studied and trained in traditional and mixed martial arts for six years and is convinced it should be legalized. “What’s more barbaric are guns,” she said. “Mixed martial arts has been a tool to defend oneself. It is a tool for self-confidence and respect. People know not to mess with me.”

The Senate has voted for the last seven years in a row to allow the sport.

Conducted inside a cage or other enclosure with a referee present, MMA bouts end when one fighter quits or gets knocked out or when judges decide after 15 or 25 minutes of fighting who the winner is.

The Assembly left the ban intact for years over fears that the sport was too violent.

Proponents also charged that Assembly Democrats, led by former Speaker Sheldon Silver, opposed it because Unite Here, a powerful food-workers union based in New York, was against it because owners of the top MMA circuit, Ultimate Fighting Championship, run non-union casinos in Las Vegas.

UFC wants to host a major card late this year at Madison Square Garden and predicts there will be other professional shows next year in Brooklyn, Buffalo and smaller cities.

Once passed, Gov. Cuomo was ready to sign the bill.

The state will collect 3 percent of gross receipts from ticket sales and broadcast rights, as well as licensing fees.
