The NBA released this today:

I saw the very end of this game and the play in question. It occurred following the jumpball in the FT circle. Terry got the ball on the floor and was tied up by Finley and Manu. Finley is seen complaining about a punch after getting to his feet. One of his teammates calms him. Pretty much the we're up 1 with 3 seconds left so let it go talk.
Now I don't care one bit about the NBA or which team wins, but it is worrisome that the officials did not observe this action during the game. It was not penalized and the game was resumed with a jumpball in the center cirlce.
With all the complaining about the playoff officiating, missing a punch was certainly not what they needed.
Ironically, it was Mark Cuban's player who did it.
