NFL Knocks Out Its Concussion Study

The league cites inaccurate data for shelving its helmet sensors. It's not wrong, but that's no reason to give up.

The National Football League has quietly announced that it is suspending a pilot program to track player concussions with helmet sensors.

The sensors track the frequency and velocity of hits to the head, and will still be used in other studies from the youth level up to college. According to the NFL’s head, neck and spine committee, the more than 11,000 pieces of data its study collected during the 2013 season were unreliable, because for the most accurate reading, hits had to be squarely on the helmet’s center of gravity.
