Dallas Cowboys defensive tackle Trysten Hill has just been suspended two games ... and it's all thanks to a punch he threw at Las Vegas Raiders guard John Simpson after Thursday's Thanksgiving game.
The NFL just made the punishment official on Monday ... saying Hill's suspension will start when the Cowboys take on the Saints this Thursday night.
In the video, you can see Hill -- without his helmet -- appear to be exchanging words with Simpson at midfield shortly after the overtime thriller ... then suddenly, things took a turn for the worse.
