NBA superstar Joel Embiid was ejected from a game Monday night ... after he relentlessly screamed in the face of a female ref.
The unnerving scene went down in the second quarter of the 76ers' tilt with the San Antonio Spurs ... after Embiid was whistled for an offensive foul.
The Philadelphia big man, wearing a mask to protect a sinus injury he suffered earlier this month, was so livid over the call, he raced to Jenna Schroeder and began melting down. He yelled at the woman repeatedly -- at one point getting mere inches from her nose.
