Self reference to Wikipedia 

I have removed the self reference (However, they cited this Wikipedia entry for the background of the event (that explains the scripted nature) as the same way the government functions.) to Wikipedia (again) for a couple of reasons:
While not explicitly covered in Wikipedia:Manual of Style (self-references to avoid), in general it says to avoid referencing Wikipdia in articles that are not about Wikipedia or those involved with it.
While the NBC sports article is referencing Wikipedia, Wikipedia is not considered a reliable source as it is user generated content.  
That NBC sports cited the Wikipedia article on WWE Capitol Punnishment is really not relevant to the event.
The whole thing is a circular reference.  Wikipedia reports on WWE→NBC cites Wikipedia→Wikipedia cites NBC as citing Wikipedia.  So really it is Wikipedia citing itself, and again, Wikipedia is not a reliable source.
