Im not sure if this is the right forum for this but the Wrestling forum was no help. One minute left in OT, that no call. I don't know how to find the video sorry. If the NBA started releasing those reports already I would be curious to see the explanation.
If you didn't see it H13 crossed V23, V23 reached in and possibly fouled H13, H13 hooked V23 and dragged him about 8 feet, V23 grabbed H13 after dribble was terminated and caused him to travel, both players looked at the nearest official and asked for a call that wasn't going to be made so resumed fouling each other followed by one final foul by V23 on the desperation heave but was released after the Shot clock violation.
The play begins at 2:48 of this clip.
