Watch: Lions' Dominic Raiola stomps on Bears' Ego Ferguson
The stomp occurred as Raiola was walking away from a pile-up with the Lions leading 10-7 in the third quarter. Ferguson then limped off the field.
In 2011, Detroit's Ndamukong Suh was ejected and received a two-game suspension for stomping a player on Thanksgiving Day. He would later apologize for the incident.
The Lions were 10-4 and tied for first in the NFC North heading into Sunday's game in Chicago.
