The Concussion Blog Original, NFL Concussion Report, is a weekly compiling of the reported head injuries in the National Football League. Concussions are added to the list each week from multiple sources to give you the reader a picture of what is happening on the field. Each week we will bring you the information along with relevant statistics. If we have missed a concussion or put one on here erroneously, let us know (we will also be using Fink’s Rule to classify a concussion/head injury).
After last week and the NFL reporting only six concussions this week picked right back up to previous levels. We have unearthed 14 concussion for Week 15; showing that last week was definitely an outlier. Since Week 11 the number of concussions per week were as follows: 16, 19, 15, 6, and 14. As my two-year old’s favorite TV show says “one of these things are not like the others”.
Our data collection, the most comprehensive since 2010, has shown that more than 50% of ALL concussions in the NFL occur after week number 9, or the back half of the season. As of this week we have surpassed the Week 1-9 total of 80; there have been 82 since Week 10. Of course the pundits will tell you that all the byes have taken place, so more teams means more concussions; true. However, as the season wears on and the accumulation of hits to the head compile, the theory of cumulative subconcussive blows eventually creates concussive episodes may also be a culprit of our bigger numbers in the second half.
Going forward into the last two weeks – wait one week (I will get that in a second) it will be interesting to see if the trend continues or if there will be another “outlier”. About that “one” week thing I just mentioned; sure there is two games left but because 67.5% of the league is done after Week 17 concussion reporting is horrible. As was explained last week, teams will not – do not – report concussions if they are not playing a game in the 1st round of the playoffs. It takes work from the media and other information gathering entities (looking at you @nflconcussions) to ferret out concussions during the last week of play. In 2010 only one concussion (of the six) was found in Week 17 that was not a playoff team and last year we found five (of the 10) that were not playoff bound. Possibly meaning that the Week 17 number is 67.5% less than to be expected (OK that may be a leap but it is truly hard to find concussions).
With the 14 concussions found last week that brings the regular season total to 162 and the overall found concussion total since camp opened to 210. The overall total is about 15 higher than last year at this time. Here are the updated stats for the regular season (last weeks numbers);

Our definition of Incidence Rate (InR) is projected concussions/45 players taking the field per team per game, our definition of Epidemiological Incidence Rate (EInR) is projected concussions/53 man roster per team.
Comparing to past seasons the following has been found after Week 15: # (2011, 2010):
- Regular Season Concussions – 162 (150, 138 )
