Here's the hit that left Bengals RB Gio Bernard completely knocked out

Absolutely brutal.

Already a vicious game, Steelers linebacker Ryan Shazier absolutely laid out Bengals running back Gio Bernard, knocking him completely out with an uncalled helmet-to-helmet.

Pittsburgh recovered the fumble and took over before turning over the ball on downs.

Cincinnati running back Jeremy Hill took offense to the play and went after the Steelers momentarily.

This chippy game just keeps getting more intense.
