This is not a vent board or any other kind of therapy. Before you hit the POST button, ask yourself if your contribution will add to the level of discussion going on.

Important notes on articles:

• Please do not copy entire articles into your post; rather, provide links to them.. We are now links-only for ALL Internet publications. If only a small portion of the article pertains to your post, Fair Use allows you to copy those one or two paragraphs, provided you cite the author's name and the publication for which he writes. Otherwise, put a link in the HTTP Link box.
• Even if you're copying a reference to an article, provide a link to the page from which the article came. We're trying to cut down on duplicate topics, and the posting process will check the link to your article to see if it's already being discussed on this board. At the very least, you'll save yourself some grief on the boards.
• If your first reaction after reading the article you're going to share is the author is uninformed / stupid / a jerk / all of the above, it's not worth sharing with anyone. Not every article needs to be discussed. The more the hair-pulling articles are discussed (e.g. ESPN Page 2), the more the authors will write hair-pulling articles.

I used to think that by plaid_pants

But I have just spent two years watching NRL, AFL and Super Rugby all season long, and the number of head injury assessments per game seems higher than what is reported in the NFL.

The linked academic study documents the following:

"In one study of three National Rugby League (NRL) clubs, a concussion incidence rate of 14.8 concussions per 1000 player match hours was reported [13], while a rate of 28.3 concussion per 1000 player match hours were reported from one NRL club over a 15-year (1998–2012) period"

Edit to include: NRL has 13 players from each side on the field for 80 minutes, so one game would equal 35 player match hours, so 1,000 match hours is about 28 games. The stats above indicate a rugby concussion rate of about 0.5 to 1.0 concussions per game. This current rugby season, my guess is that players are taken off the field to be assessed for concussions at a rate of about 3 per game.
