The team later announced that Hayward fractured his ankle.
Hayward's left leg bent awkwardly after he went up for an alley-oop pass, collided with LeBron James and collapsed under the basket with 6 minutes, 45 seconds left in the first quarter. Teammates and Cavaliers players, including James, rushed to check on him as he was stretchered from the court.
