The family of P.E. teacher James Mohr, 23, told the New York Post that Mohr, dressed in Jets gear, was walking through the MetLife Stadium parking lot after New York's 37-10 victory over the Chiefs last Sunday when he heard the offensive taunts.
"Our other brother is a fireman, and my father is retired FDNY, so you can understand why a 9/11 comment would especially irk him," Mohr's sister Anna said, according to FoxSports.com. "He was shocked anyone would actually say something like that."
The Post said up to seven people jumped Mohr, and cited a police source as saying that at least one was wearing a Chiefs jersey. Mohr underwent hours of surgery Tuesday at Hackensack University Medical Center to repair a fractured jaw, cheekbone and eye socket.
The newspaper said a New Jersey man was arrested on an assault charge in connection with the attack, and an investigation is ongoing.
