Catastrophic brain injuries among high school football players appear to be increasing, according to data collected by the National Center for Catastrophic Sports Injury Research at the University of North Carolina.
Despite a widespread educational effort and rule changes designed to make the game safer, 13 high school football players suffered catastrophic brain injuries nationally in 2011, the most since the center began tracking them them in 1984.
The three highest yearly totals for football-related catastrophic brain injuries have come in the last four years.
