Giants’ RB Andre Brown left yesterday’s game with concussion-like symptoms and tweeted shortly after from the locker room that “everything is ok.”

It turns out, everything is not ok. Tom Coughlin confirmed today that Brown does indeed have a concussion, sustained while getting his head bounced off the turf while returning a kickoff .

Our friend Tom Rock of Newsday tweeted today that the NFL may look to fine Brown for engaging in social media during the course of a game….

Rock also reports that the original tweet has been deleted.
