2012 NFL Concussion Report Week 2

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).

EDIT: Francis Coye of OAK was added after report, making 12 concussions in Week 2.

There has been interest in the concussion “count” from the NFL for various reasons, I for one am interested in seeing how the culture change and fine system are effecting the overall numbers in the league.  I am also very interested in how the teams/league are reporting the injury.

When this started we used the Official Injury Report (OIR) from the NFL, but quickly found – via data searches – that many of the concussions were not listed because the players were going to play/practice thus not listed.  In 2010 we relied heavily on the general media to ferret out concussions from teams.  From recollection it was about 50% of concussions were found this way.

Last year we found that there was a sharp decline in the discrepancy of OIR listed and media listed concussions, most were on the OIR, a good sign.  Not only because they were more open with the disclosure, but it indicated that the player may not play in the upcoming week; the proper protocol.  Looking back it was about only 25% of concussion that were not on the OIR.

This year is a bit of question thus far; simply because the OIR’s in the past on Wednesday (when OIR’s are due) would list the injury and the status.  As of week one and two there has been listings of the player and the status, but the injury has not been listed.  The injuries are listed later in the week or by Sunday so we have been trying to confirm an actual injury count though the methods of 2010.

Because of this change in methods, there may be times when a previous week is adjusted due to fining a concussion after the fact.  Case in point last week; we listed 10 concussions, however after the injuries were finally filled in there was an addition, Richard Goodman of San Diego.  That brought the number to 11 from week one.  In the cases where there is a change in overall numbers I will make note of it.

In a side note, we are also collecting helmet data – identifying the helmet worn during concussion – and there appears to be fewer players wearing the very old style helmets (Riddel VSR4 and Schutt AiR Advantage).  Along with that we have noticed quite a spike in the Rawlings Quantum being worn (few concussed thus far).  Other helmet that has seen an increase of time on the field are the Schutt Vengeance (worn by Eli Manning) in its first year of existence and the Riddell 360 (second year).  We have also noted the Simpson helmet on the field as well.

Now on to the stats for week two, the total concussions found was 11, bringing the regular season total to 22 and from the preseason on the total now sits at 70.  Here is the break down the ()’s indicate last weeks numbers;

  • 22 Concussions/head injuries (11)
  • 11.0 Concussions/week (11.0)
  • 187 Projected Concussions (187)
  • 0.73 Concussions/game (0.73)
  • 12.99% InR (12.99)
  • 11.03% EInR (11.03)
  • 12 Offensive (5) – 10 Defense (5)
  • Positionally Speaking
    • QB – 0, RB – 2 (1), TE – 3 (0), WR – 4 (3), OL – 3 (3), DL – 2 (1), LB – 3 (1), DB – 5 (3)
  • Team Breakdown
    • CLE, DET, NYJ, OAK, WAS – 2
    • ATL, DAL, GB, IND, KC, MIA, MIN, NE, NO, NYG, SD, 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 # (2011, 2010):

  • Regular Season Concussions – 22 (17, 24)
