NL Ruling Please

[InTheDark]

$2-5 NL. Player A raises to $40, I raise to what I assume is his stack, $140. All fold to A who sez 'call' but doesn't move any chips. Turns out his stack is $155 total but the dealer has already brought the turn and river. The board is 5 4 3 5 3 rainbow and I hold KK. I want his last $15 since I'm quite sure he has AQ, as he stated, but not at the risk of any new board cards. I STFU and the dealer pushes me the pot, leaving him with $15.

I've got 20 years of casino poker under my belt and I have not a clue how a floorman might rule here. I'm pretty sure I made the right play, EV wise. Any ideas?
