2011 NFL Concussion Report Week 6 (Correction)


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).

At this point last year we were all digesting and inspecting the hit that Dunta Robinson levied on DeShaun Jackson, and the League was beginning the process to fine those offenders that needlessly took risks that could result in injuries.  There were 52 concussions in the regular season (8 in the preseason for a total of 60) last year at this point.  So a year later what has been observed; 55 concussion injuries in the regular season (36 in the preseason for a total of 91).  From a glance there has been little change in the regular season, the high preseason numbers could be chalked up to better awareness of the press  and perhaps the players more willing to come forward.  For perspective it took ten weeks to reach the 91 concussion mark last year.

Some may wonder whether this indicates a higher actual incidence of concussions, observationally yes, but practically the best answer is no.  If you recall my caution heading into the regular season (TCBCR Preseason Wrap) I felt that the increase in the preseason was due to multiple reasons, none of which were related to increased injury rate.  Prior to that I hypothesized that we would see nearly 200 total reports this year and again it would be mainly due to increased awareness and reporting; getting us to a more “true” incidence rate.

Credit is due to the journalists and reporters; after opining that to get better numbers we would have to rely more upon them than teams, that has indeed happened.  Credit is also due to you the reader as many of you have sent in emails or tweets that have clued us into injuries, so thank you.

Putting the recent Vick injury aside let us take a look at the numbers, also appearing in Will Carroll’s Med Check this week on SI.com (quick note three two teams have yet to report a single concussion through the 10 weeks of games (preseason included), very interesting and either fortunate or inaccurate, they are: Cincinnati, Kansas City and Miami) upon further review Kansas City did report Jackie Battle as head injury on OIR;

  • 55 Concussions/head injuries (44 W5)
  • 9.17 Concussions/week (8.80 W5)
  • 156 Projected Concussions (150 W5)
  • 0.61 Concussions/game (0.58 W5)
  • 10.82% InR (10.39 W5)
  • 8.19% EInR (8.82 W5)
  • 24 Offensive – 31 Defense
  • Positionally Speaking
    • QB – 3, RB – 4, TE – 6, WR – 4, OL – 7, DL – 3, LB – 11, DB – 17
  • Team Breakdown
    • OAK, CAR – 6
    • OAK – 5
    • ATL – 4
    • BAL, DET, IND, NYG, PIT – 3
    • JAX, MIN, NE, NYJ, PHI, SEA – 2
    • ARI, CHI, CLE, DAL, DEN, KC, GB, NO, SD, SF, STL, TB, TEN – 1
    • BUF, CIN, HOU, KC, 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.
