There are 17 weeks and 256 games in the NFL season. And this year, there were 225 concussions.

Josh Begley, data artist at The Intercept, just released a haunting film showing footage of the hits that led to some of the most dangerous head injuries that occurred in the pre-season and regular season football games this year.

"I have been tracking these injuries all season. Using a variety of methods, including reviewing daily injury reports from NFL.com, I have created what I believe is the most complete dataset of individual concussions sustained during the 2017-2018 season," Begley wrote. "The resulting film, 'Concussion Protocol,' is a visual record of every concussion in the NFL this year."
