The average person will never experience G-forces of over 5.0, but that’s far from the case in the NFL.

As the number of reported NFL concussions continues to rise, BodyLogic examined some of the most brutal hits in recent history and put together a chart showing the estimated G-forces each player’s brain was subjected to.

Leading the list is former Miami Dolphins quarterback Matt Moore, who was on the receiving end of a massive hit from Pittsburgh Steelers linebacker Bud Dupree during a wild-card game in January 2017. The study estimates the hit exerted a G-force of 87.4g to Moore’s brain, though he was allowed to return to the game one play later (the NFL later concluded that the Dolphins didn’t follow concussion protocol).
