EAST RUTHERFORD, N.J. - A group of Kansas City Chiefs fans severely beat a New York Jets fan after the Jets' 37-10 victory Sunday in New Jersey, the New York Post reported . A woman in a group of fans yelled an obscene comment about New York and "You all deserved what happened on 9/11!" before the attack, 23-year-old James Mohr’s family told the newspaper. According to the report, Mohr sustained a fractured jaw, cheekbone and eye, and also has bleeding on the brain. He went hours of surgery to repair his face. A police source told the Post at least one of the assailants was wearing a Kansas City Chiefs jersey. "This is an unacceptable attack on one of our guests," a Giants Stadium rep told the Post, "and we have been working with the New Jersey State Police to make sure the man arrested is prosecuted to the fullest extent of the law."
