The number of players with concussions listed on weekly NFL injury reports has swelled in recent years. According to Concussion Watch
, 170 players were listed on injury reports for concussions during the 2012 season, nearly double the 92 reported in 2009.
Similar increases have been reported at lower levels of football. At the youth level, more than half a million concussions are reported
