That's the word from US Soccer Director of Referee Development, Paul Tamberino in an article on MLS' website. Tamberino is the same guy that speaks on US Soccer's Referee Week in Review as well. He says that Brad Evans did not intentionally deceive referee Jair Marrufo, as the play only took seconds to actually play out on the field. Still, Tamberino says that referees need to be aware of where the ball went out, especially in the attacking third and so late in the game. And while the linesman was closer to where Evans was, Tamberino says that the responsibility in this situation goes on the center referee Marrufo.
This isn't a surprising report, as I think anyone with eyes to see saw that Evans added at least 10 yards onto where the ball went out. I also think most people expected this incident to be in this week's report due to the outcome of the play and the result as a whole. While it's nice to see them make an example of it, it doesn't take the bitterness out of the goal or the loss.
