Boston Celtics forward Gordon Hayward suffered a horrific ankle injury just six minutes into his debut with the team as they lost 102-99 to the Cleveland Cavaliers.
Hayward had been attempting to finish off an alley-oop pass from Kyrie Irving when he collided with LeBron James and Jae Crowder on the way up before landing awkwardly.
Players looked visibly shaken as Hayward lay on the court in agony with a clearly twisted left ankle.
The Celtics later confirmed that the 27-year-old had suffered a fractured ankle - a heavy blow for the team, who had hoped their star recruit would help to close the gap on the Cavaliers in the Eastern Conference.
The Celtics were leading 12-9 when Hayward went down, but soon lost the momentum as Cleveland pushed in front to lead 54-38 at half-time.
Boston fought back in the third to narrow the gap to 72-71 going into the final quarter, but could not do enough to take the win in the season-opening game.
