A federal judge in Connecticut has dismissed a lawsuit by 60 former professional wrestlers, many of them stars in the 1980s and 1990s, who claimed World Wrestling Entertainment failed to protect them from repeated head trauma including concussions that led to long-term brain damage.

A doctor who will be portrayed by actor Will Smith in the upcoming movie, "Concussion," told a Tampa audience how his research into brain injuries has dramatically changed how professional football approaches players.
