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

Allen Sills said Tuesday that “about 37 percent” of the 379 concussion evaluations during the preseason and regular season were “initiated by a self-report.” Sills said it was about 20 to 22 percent a year ago.

He called that increase “a positive development.”

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 said it’s impossible to “capture 100 percent of concussions.”
