FILE - This Nov. 7, 2010, file photo shows Philadelphia Eagles wide receiver DeSean Jackson reacting after catching a pass in the first half of an NFL football game against the Indianapolis Colts, in Philadelphia. In a series of interviews with The Associated Press, representatives of the NFL, the NFL Players Association and the four equipment companies that make every helmet worn in the league all agreed there's no such thing as a football helmet that eliminates concussions _ nor is one on the way anytime soon.
