The league is looking into an incident that occurred as Green Bay Packers safety Nick Collins made his way from the field to the locker room after Monday night's game at Soldier Field.
The NFL is "in the process of reviewing the facts," senior VP of public relations Greg Aiello told AP.
The Milwaukee Fox affiliate has broadcast video showing Collins yelling at a fan and throwing what looks like a mouthpiece at the fan as he left the field. Collins later told the station that the fan spit on him and used a racial slur. Teammate Donald Driver restrained Collins and may have prevented the incident from escalating. Collins later apologized, according to the station, for "losing his cool."
When asked whether the matter would fall under the jurisdiction of the Bears, Soldier Field security or NFL security, team spokesperson Scott Hagel said, "everybody will be reviewing it. We work together."
If Collins version of the events is accurate, the fan should be banned from Soldier Field for life.
