In a No Disqualification match where everything goes, AJ Styles (with Luke Gallows and Karl Anderson in his corner) faced Aleister Black.
This match included weapons (chairs, tables, kendo sticks) since there were no rules. Gallows and Anderson got involved and Black had to fight them, but the numbers were too much for him. Styles was about to hit the phenomenal forearm, but the lights went out and The Undertaker appeared in the ring. Taker stifled Styles, the lights went out and he disappeared. Taker's help allowed Black to hit the Black Mass and then set Styles.
