NBA: Rockets stun Warriors, Hayward suffers gruesome injury in Celtics loss

The Golden State Warriors' title defence got off to a losing start against the Houston Rockets, while the Boston Celtics went down to the Cleveland Cavaliers and lost Gordon Hayward to a serious injury. Golden State were beaten 122-121 by Houston, who rallied 34-20 in the fourth quarter of Tuesday's NBA season opener. NBA Finals MVP Kevin Durant had a chance to win it on the buzzer and he actually hit a shot to give the Warriors a 123-122 lead, but after further review, the ball was still on the Warriors star's fingertips when time ran out giving James Harden and the Rockets victory.
