NEW YORK – It’s official now, with a location and everything: Paulie Maligniaggi and Artem Lobov will headline Bare Knuckle Fighting Championship 6 on June 22 at Florida State Fairgrounds Entertainment Hall in Tampa, Fla. But before the two heated rivals step inside the ring, they held a news conference on Monday at Dave & Buster’s in Times Square, and it went how you’d expect. Neither former boxing champion Malignaggi nor former UFC fighter Lobov had anything nice to say about each other.
