After having quite a successful performance in their preseason opener, the Oakland Raiders responded to their Week 1 win against the St. Louis Rams with a relatively mediocre performance on the road against the Minnesota Vikings on Saturday, August 22.

Despite having just one penalty against the Rams in the previous week, Oakland struggled to stay disciplined as a unit, and in turn, accumulated 13 penalties for over 100 yards over the course of the game.
