Tom Brady doesn't confirm wife's concussion claim, but doesn't deny it either

Gisele Bundchen, the wife of Tom Brady, made waves in May when she told Charlie Rose on “CBS This Morning” that Brady had suffered a concussion during the 2016 season. It was news to many, as Brady had not appeared on the New England Patriots injury report at any point last year with a brain injury. The NFL, working with the NFL Players Association, investigated the Patriots and its medical staff and determined that the star quarterback did not have a concussion last year, a case that certainly was closed a lot faster than the last Brady-related investigation the league began.
