One day after the star tight end underwent back surgery, the New England Patriots placed him on injured reserve, according to a person with access to the NFL’s internal transaction wire. The Patriots already used their one designated-to-return spot on backup quarterback Jacoby Brissett , so placing Gronkowski on IR means he cannot play again this season. http://www.usatoday.com/story/sports/nfl/patriots/2016/12/03/rob-gronkowski-back-surgery-injured-reserve-season-officially-over/94903356/
