NFL players no longer can wear exposed "hoodies" over their shoulder pads, according to a series of adjustments that will appear in the 2016 edition of the NFL rule book.
In addition, assistant coaches are now prohibited from entering the field of play.
The final version of the book has not been published, but a league source confirmed the changes to ESPN's Ed Werder.
The "hoodie" rule was deemed necessary after receiver James Jones debuted the style last season while playing for the Green Bay Packers. The hood at times blocked Jones' nameplate on his back.
