One of the NFL's harshest critics crashed a Thursday news conference the league planned to use to tout its funding of advances in concussion diagnosis and prevention techniques.
Chris Nowinski, executive director of the Concussion Legacy Foundation, dropped by for the NFL's annual health and safety update ahead of Sunday's Super Bowl between the Broncos and Panthers to listen as league-affiliated Dr. Mitchel Berger downplayed the link between football and chronic traumatic encephalopathy, or CTE.

Nowinski has been critical of the NFL's decision last month to cut funding to Boston University's research efforts to develop testing that would diagnose CTE in patients who have not yet died.
