Hayward's leg was put in an air cast and had to be stretchered off because of the severity of the injury. Video of the injury is below, but we have to warn you, it is extremely graphic.
The injury is similar to the injury suffered by Oklahoma City Thunder forward Paul George during a Team USA scrimmage in 2014. He returned to play in the final six games of that season for the Indiana Pacers.
