The NFL has fined Vikings safety Harrison Smith for his horse collar tackle on Redskins quarterback Robert Griffin III last Sunday, according to a league spokesman.

Smith was fined $15,750, two weeks after he was ejected from a game for shoving a referee. 

Griffin was scrambling toward the sidelined when Smith dragged the quarterback down from behind, grabbing him around the collar. Griffin scored from seven yards out a play later. 

In the preseason, Smith was fined $21,000 in the preseason for a shoulder-to-head hit on a defenseless player.
