Brady mum on concussion claim

New England Patriots quarterback Tom Brady on Friday declined to confirm or deny whether he sustained a concussion in 2016, as the superstar's wife Gisele Bundchen said in May. The NFL has faced growing scrutiny in recent years linked to the issue of concussions and head trauma, with the league agreeing in 2015 on a $1 billion settlement to resolve thousands of lawsuits by former players suffering from neurological problems.
