HCR Update from Mark Sanna: The revelations that hits to the head may lead to long-term brain damage have rocked the football world at all levels, alarming coaches, players and their parents and forcing the NFL and the NCAA to tighten safety standards. Given the consequences of the injuries, lawyers, too, have taken note, including those representing the 5,000 retired players who sued the NFL over claims that the league hid the dangers of concussions. The notoriety of that case also prompted George Washington University’s law school to start what it said was the first course devoted to the legal implications of traumatic brain injuries.
