Apparently Riley didn't even know about this until 11am this morning and he's not happy about it. That sounds true, I don't think they would have let Tommy Armstrong make all of those stupid comments. Obviously there's a team policy regarding this sort of thing.
Riley said he was disappointed that they did not come to him and tell him what happened. He then went on to say that he did not ask them why they didn't come to him. Seems to me that would probably be one of the first questions asked. I fully expect the investigation to take 2 weeks and then depending on what is discovered (do the Huskers make a bowl game) it could be extended.
