The New York Times published a story Thursday based on the paper's investigation into the NFL's concussion research from 1996 to 2001 that was used in 13 peer-reviewed articles and "held up by the league as scientific evidence that brain injuries did not cause long-term harm to its players."
The Times alleges that its investigation shows "that more than 100 diagnosed concussions were omitted from the studies -- including some of the severe injuries to stars like quarterbacks Steve Young and Troy Aikman." The story then states the data was then used to calculate the rates of concussions sustained, which made "them appear less frequent than they actually were.
