The New Orleans Pelicans announced on Friday that star forward Zion Williamson will be out indefinitely with a broken finger and general manager David Griffin says NBA referees are to blame, claiming that they were warned about doing a better job of protecting the second-year player.

"Zion is left-handed so it's a fairly significant situation for him," Griffin told reporters. "I'm really frustrated because this was avoidable. We told the NBA through every means available to us, through sending in film, through speaking to everybody in the officials department and everybody in basketball operations, that the way they were officiating Zion was going to get him injured."
