Lions lineman Dominic Raiola is known as a dirty player but what he appeared to do against the Bears on Sunday is completely unacceptable and warrants a suspension.

At the end of a play, Raiola was walking away from the pile and appeared to intentionally step on Ego Ferguson's ankle.

An excellent job by Fox's broadcast to zoom in and spot Raiola almost consciously making a decision to stomp the defensive tackle's ankle.

What an absolutely abhorrent play. Totally worthy of a significant punishment from the league.
