Memphis Grizzlies guard Grayson Allen was ejected during a summer league for being too physical.

During the game, Allen became entangled with Celtics rookie Grant Williams, forcibly pushing him off a backscreen to draw his first flagrant foul. Later, Allen made another risky move when Williams went up for a lay-up. Allen swiped to make a play on the ball but instead elbowed Williams in the head, which earned Allen his second flagrant foul and subsequent ejection. Allen exhibited this behavior toward Williams after missing two free throws.

Allen was a polarizing player at Duke as well. He was suspended for several games for intentionally tripping players, which led coach Mike Krzyzewski to taking away his captaincy during the 2016-17 season, per USA Today.
