Just days before the Super Bowl, 48 percent of Americans say they’d encourage a child who wanted to play football to play a different sport due to concerns about concussions — up 8 points since the same question was asked four years ago, according to the latest national NBC News/Wall Street Journal poll.

That includes 46 percent of parents with a child in the household (up 9 points since 2014), 53 percent of mothers (up 13 points) and 39 percent of fathers (up 6 points).
