Boston Celtics guard Marcus Smart (eye) has been ruled out for Friday's game against the Detroit Pistons. Smart continues to deal with an eye infection, but will hopefully be back soon. Gordon Hayward (foot) is questionable for Friday, so the Celtics could be thin for this one. Brad Wanamaker (ankle) and Grant Williams could see over 25 minutes each with Hayward and Smart possibly sidelined. Fantasy owners will be without Smart for at least one more game.
