This one appears to be an accident.
Duke's Grayson Allen was charged with a foul in the Blue Devils' 72-64 victory over Pitt on Saturday as it appeared he extended his right foot and tripped up Jamel Artis.
Watch the incident below:
Allen has a history of tripping incidents going back to February 2016, which included games against Florida State and Louisville. Last December, Allen served a one-game suspension for tripping an Elon player. Saturdays' play looks the least intentional and most certainly not Allen's fault.
Allen finished the game with 21 points and six assists.
