Former NFL player Kevin Turner walks to the U.S. Courthouse Tuesday, April 9, 2013, in Philadelphia for a hearing to determine whether the NFL faces years of litigation over concussion-related brain injuries. Thousands of former players have accused league officials of concealing what they knew about the risk of playing after a concussion.
