2011 NFL Concussion Report Week 9

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).

Last week there was an anomaly with only 2 reported concussions, this week was the polar opposite.  There were 12 reported incidents this week (2 in practices).  Which one is more accurate?  Week 9 would be the answer.

Week 9 was the first week the officials were asked to have heightened awareness about spotting brain injuries on the field.  As we mentioned on Monday it showed promise; but looking at the averages it was only slightly more effective.  However the move was a good one and in the long run I believe it will result in more cases being caught.

A lot of the feeling about this week have been made known already, no need to repeat it; so without further delay here are the updated statistics on concussions in the NFL (116 total from the opening of camp);

  • 80 Concussions/head injuries (68 W8)
  • 8.88 Concussions/week (8.5 W8)
  • 151 Projected Concussions (145 W8)
  • 0.59 Concussions/game (0.56 W8)
  • 10.49% InR (10.03 W8)
  • 8.91% EInR (8.52 W8)
  • 37 Offensive – 43 Defense
  • Positionally Speaking
    • QB – 3, RB – 6, TE – 9, WR – 8, OL – 11, DL – 7, LB – 14, DB – 22
  • Team Breakdown
    • OAK, CAR – 6
    • PHI – 5
    • ATL, BAL, CLE, IND, NYG – 4
    • DEN, DET, MIN, NE, NYJ, PIT, SD, SEA, STL, TEN – 3
    • GB, JAX, NO, SF – 2
    • 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.

Notes:  Miami and Cincinnati have yet to report a single concussion since preseason…  DB’s compile 27.5% of regular season concussions and 25% of concussions overall…  RB’s have shown a concussion incidence decline from preseason (7.5% of RS and 13.79% overall)…  Mohamed Massaquoi was listed as a 2nd concussion (different from official reports); because a player cannot return to play unless he has been cleared, therefore we are classifying it as his 2nd…  Of the 116 overall concussions there is a 50.8/49.2% split offense/defense…
