Nothing in what you've linked says Armstrong had a concussion.http://www.cornnation.com/2014/8/9/5986271/nebraska-huskers-football-first-saturday-practice-report-tommy-armstrong-adam-taylorHas there been a single news source that says Tommy Armstrong suffered a concussion?
And I don't take too much stock in the "news sources" reporting/not reporting, especially since, 1. Bo has never been shy about forbidding reporters if they do not follow his protocols (irony). And 2. There weren't any concussion reports about Joe Ganz and he's admitted he "doesn't remember" the Gator Bowl winning drive.
