Dealer mistake: OK to go on with the hand?

[ZPinhead]

What if it's not the flop that's exposed early, but the river. Example:

2 players (I held AJo)
Board: 3 A K 8
Player 1 bets, I raise, before player 1 (in #1 position) calls the dealer burns and turns the river (an A), realizes his mistake and tries to cover the card with his hand. Player 1 had not seen the card, but it has been exposed. The dealer then shows the A and puts it back in the deck, lets player 1 call and redeals the river (a 2). Check/check and of course player 1 shows K8o.

I wasn't until later that I kicked myself for not calling for the floor. Would the rule that was sited apply to an improperly exposed river card also?

Yes, The river comes back. The river card is shuffled back into the deck, the burns are left alone. One cut, no burn, (there's already been a burn), and the top card comes out as the "new" river. Anytime there are cards that are pre-mature in coming off the deck they come back.
