2013 Week 2 NFL Concussion Report

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).

It is early in the year but there are two things that strike me, already.  Mind you that it IS early I have not seen any “gaming of the system” to produce my observations.  This leads me to my first take from two weeks:

  • While watching the game and looking at Twitter/online there have been more in-game concussion evaluations publicized then the past three years.  Often I have heard/read “X player is being taken to the locker room for a concussion evaluation.”  This is indeed a good thing.  I don’t know if this was a directive from the league to make sure people know they are trying (I have asked in previous years to be as transparent as possible with this) but what this does in my mind is let people know this is the proper protocol for all levels.  Certainly there have been players returned to the game after passing the test, which I am fine with.  However, there has been a case of a player being removed, passed the test and then having symptoms on Monday, which is also understandable.
    • It should be noted that if an athletic trainer or doctor at levels below the NFL have enough information to remove a player for a test more than likely they should not be returned to play.  But, this also speaks to the need for qualified medical personnel on the sidelines.  Personally speaking, I have had one in-game evaluation due to overhearing that player state he was dizzy and had a headache, only to find upon evaluation it was a dehydration situation.
  • Secondly, I am puzzled and could be swayed to impressed with the low number of concussions reported thus far.  I have watched my usual amount of games with an increase in data mining during games and don’t see the previous mechanisms of euphemisms and down right avoidance of classifying concussions.  I have no clue as to why this is, but we should continue to note this early trend.  Check back about Week 6 to see where they are.
    • It bears repeating that concussions in all levels have shown to exponentially increase as the year wears on due to what we believe to be an accumulation of subconcussive blows.

Now on to the Week 2 numbers (indicates previous weeks numbers):

  • 6 concussions/head injuries found from Week 2 (5)
  • 11 regular season concussions noted (5)
  • 66 total  concussions in 2013 (60)
  • 5.50 Concussions/week (5.0)
  • 93.5 Projected Concussions (85)
  • 0.37 Concussions/game (.33)
  • 5.77% InR (5.77)
  • 5.01% EInR (5.01)

Running Totals for Regular Season:

  • 5 Offensive (2) – 6 Defense (3)
  • Positionally Speaking
    • QB – 0 (0), RB – 1 (0), TE – 1 (1), WR – 3 (1), OL – 0 (0), DL – 0 (0), LB – 1 (1), DB – 5 (2)
    • Team Breakdown
      • NYJ, WAS – 2
      • CAR, GB, HOU, PHI, NYG, SF, TEN – 1

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 2: # (2012, 2011, 2010):
    • Regular Season Concussions – 11 (24, 17, 24)
