Steelers safety Damontae Kazee has just been sidelined for the rest of this season ... after the NFL slapped him with a suspension for his dangerous hit on Michael Pittman Jr. over the weekend.
In a statement announcing the ban on Monday, the league said the blow -- which happened in the second quarter of Pittsburgh's loss to Indianapolis on Saturday -- was "a serious violation of the playing rules."
The play was one of the most violent of the season -- Kazee left his feet and made contact with Pittman Jr.
