Duke University has indefinitely suspended guard Grayson Allen after he intentionally tripped Elon's Steve Santa Ana during the first half of last night's game. This is the third time that Allen has been involved in a tripping incident in the last 10 months. The other two occurred on Feb. 8 against Louisville and Feb. 25 against Florida State. Duke head coach Mike Krzyzewski sat a visibly emotional Allen the remainder of the first half and the beginning of the second half. After the game, Krzyzewski said that Allen's actions were "unacceptable and inexcusable" and that Allen apologized to both Santa Ana and Elon coach Matt Matheny after the game.
