While fighting for a possible rebound situation, the referees call a personal foul to White 18 for creating an illegal contact against Red 27. The referees become uncertain if the foul should be upgraded to unsportsmanlike or disqualifying foul and decide to check the IRS.
F.3.3: The following game situations may be reviewed at any time of the game:
Whether a personal, unsportsmanlike, or disqualifying foul met the criteria for such a foul or shall be upgraded or downgraded or shall be considered as a technical foul.
Article 38.1.1 A disqualifying foul is any flagrant unsportsmanlike action by players, substitutes, head coaches, assistant coaches, excluded players and accompanying delegation members.
Article 38.2.3 Any of the above persons who are guilty of flagrant acts of aggression on opponents or referees shall be disqualified.
Outcome: Correct decision from the referees. The contact created by White 18 fulfilled the criteria to be considered a disqualifying foul.
