The NFL sent a memo Wednesday warning teams against staff interactions with opposing players in the aftermath of Sunday's confrontation between 49ers linebacker Dre Greenlaw and Eagles security staffer "Big Dom" DiSandro.
“The playing rules of the National Football League … clearly prohibit non-player personnel — coaches, trainers, equipment staff, security officers or others — from making physical contact with, taunting or directing abusive or insulting language toward opposing players, game officials or others involved in a game,” the statement reads as reported by NFL Network.
