Promoters aren’t commenting on who will appear on the August 16 boxing event booked to take place at the Chicago White Sox’ U.S. Cellular Field stadium. Word on the street is IBO light heavyweight champ Andrzej Fonfara will figure prominently. Also this unofficial video popped up on YouTube, but officially? “You’re all going to have to wait,” says Frank Mugnolo of Round 3 Productions. “I don’t even know yet. As soon as we make decisions, we’ll announce them. All I can promise you is this is going to be an unforgettable show and we’re very proud to be putting it on in the city.” The card is expected to be the 2013 finale for ESPN2 Friday Night Fights.
