2011 NFL Concussion Report Week 8

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).

Through Week 8 we have seen a very slight increase of reported concussions, 6.25%, as compared to last season.  Interestingly 2011 Week 8 provided us with only two reported concussions, yes only 2!  Granted there were six teams on bye, but there has been six teams on bye the last three weeks, so that would not be a factor.  The only teams that were on bye that have been producing the best (most likely accurate) reports were Atlanta and Oakland (14.7% of reported concussions).  Certainly that could be a small factor.

Looking back to last season, Week 8 2010 also produced the lowest number of concussions reported, four.  Maybe it is just the time of the year?  No matter how you look at it, it seems very strange that we recorded 11 concussions in three consecutive week and then it suddenly drops to 2.

There has been one factor brought up to me that may hold some weight; Kris Dielman.  One week after the bungled concussion management of the Charger offensive lineman there is an abnormally low number of concussions.  Before we get into conspiracy theories maybe it could be that there were only two incidents, because there were only two incidents.

Here are the updated stats for the regular season (104 total since training camp);

  • 68 Concussions/head injuries (66 W6)
  • 8.50 Concussions/week (9.43 W6)
  • 145 Projected Concussions (160 W6)
  • 0.56 Concussions/game (0.63 W6)
  • 10.03% InR (11.13 W6)
  • 8.52% EInR (9.45 W6)
  • 32 Offensive – 36 Defense
  • Positionally Speaking
    • QB – 3, RB – 4, TE – 9, WR – 6, OL – 10, DL – 5, LB – 12, DB – 19
  • Team Breakdown
    • OAK, CAR – 6
    • ATL, IND – 4
    • BAL, CLE, DET, MIN, NYG, PHI, PIT, STL – 3

    • ARI, CHI, DAL, KC, NO, TB – 1
    • BUF, CIN, HOU, MIA, WAS – 0

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.
