Duke big man Kyle Filipowski appeared to trip UNC forward Harrison Ingram during their game in Chapel Hill's Dean Smith Center on Saturday.
The incident occurred with roughly six minutes left in the first half, after Duke's Jared McCain grabbed a defensive rebound off an Ingram missed jumper. Ingram and Filipowski got tied up and fell to the ground. Ingram got up first and started running back on defense.
He tried to run past Filipowski, who was turned in the opposite direction. Filipowski then lifted up his right leg, and Ingram slowly stumbled to the ground before getting back up.
