I'm not sure how I feel getting my news from a website called Rumors & Rants, but this article says that according to sources at Manning Passing Academy, Johnny Manziel was sent home. Apparently, after a night of hard partying he showed up late on Saturday and was dismissed by Archie Manning.
Another article from houmatoday.com stated that "a Manning Camp official said Manziel was sick and returned home Saturday afternoon. The official wouldn't say if it was Manziel's decision to leave the camp early or give a reason for the quarterback's illness."
We'll be hearing a lot more about the validity and details of this story today, but it's something to keep an eye on for now.
