Removing jersey

[Bad Zebra]

Had a somewhat similar situation last night. Player V22 was called for a hand check and (surprise) disagreed. He pulled out the front of his jersey and covered his face in frustration. One of my partners wanted to whack him. I disagreed and said the rule pertains to REMOVING the jersey. I think we would have been justified in whacking him for unsporting behavior but I opted to tell him to tuck it back in during the ensuing free throw and not pull it out again or I would whack him. It was early in a regional playoff game. He wasn't a problem the rest of the night.

Would anyone whack him? He eventually fouled out in the 4th Q.
