Against a vicious St. Louis Los Angeles Rams defense, Minnesota Vikings quarterback Teddy Bridgewater was the recipient of not one, but two clearly dirty hits.
The first one was earlier, when a Rams defender went low at Bridgewater's knees.
And the latter was above, where Bridgewater gave himself up, sliding forward and the Lemarcus Joyner threw an elbow and shoulder into the quarterback's head, knocking him completely unconscious.
Bridgewater was diagnosed with a concussion and did not return to the game.
