The number of diagnosed concussions suffered by NFL players increased nearly 16 percent this season over last season, and the rate of injuries suffered by players during Thursday night games exceeded the injury rate in other games.
Those were among the key developments as the NFL released its preliminary injury data Friday for the 2017 preseason and regular season.
“Certainly we’re disappointed that the concussion numbers are up. … We take this as a challenge because we’re not going to be satisfied until we drive that number much lower,” Allen Sills, the NFL’s chief medical officer, said in a conference calls with reporters.
