After a long run by Redskins running back Alfred Morris, Lauvao flew in to lay out Ravens cornerback Dominique Franks. With Lauvao laying face first in the ground, Ngata took a couple of steps toward the lineman and kicked him.
Ngata wasn't penalized on the play, and Lauvao wasn't injured.
"When I saw Lauvao do that, I was just kind of pissed that he was doing that and just nudged him -- kind of the heat-of-the-moment thing," Ngata said. "That was the only thing. I was just trying to protect my own player. No disrespect to Shawn because we know each other. It was the heat of the moment, and [I] just was mad that he tried a late hit."
Ngata has been disciplined by the NFL in the past. In 2010, he was fined $15,000 for hitting the face of Ben Roethlisberger, which broke the nose of the Pittsburgh Steelers quarterback. In 2011, Ngata was fined $15,000 again for lowering his helmet into the back of New York Jets quarterback Mark Sanchez.
