NEW YORK — The NFL’s chief medical officer says more than a third of concussion evaluations so far this season are a result of players indicating they have symptoms, a much higher percentage than last season.

Allen Sills said in a conference call with reporters Tuesday that "about 37 per cent" of the 379 concussion evaluations during the pre-season and regular season have been "initiated by a self-report." Sills said it was about 20 to 22 per cent a year ago.

Sills also said the rules for checking for a concussion were followed properly for Indianapolis Colts quarterback Jacoby Brissett on Sunday, when he was allowed to return to a game after a hit to the head. After the game, it was determined he did have concussion symptoms.

Sills says it is impossible to "capture 100 per cent of concussions."
