Now we know why Johnny Manziel missed a 9 AM appointment for concussion protocol on Sunday morning. The night before, he was partying in Vegas, wearing a blonde wig, fake mustache, and glasses under the alias "Billy". The jig was up when he did not have enough cash on him and had to use his credit card. Furthermore, that night he posted a photo of him at home with his dog on Instagram, and manually entered the location as Avon, Ohio with the hashtag #SaturdayNights. It does not appear that Manziel went through the trouble of entering his purported "location" on any of his other recent Instagram posts.
