Yes, unless room rule allows for it. VERY significant action has taken place and Dead Hand = "doesn't contain the proper number of cards for that game."
Being on the B this player could've received his 2nd card and the hand could've carried on after, but he out of luck in this spot.
Also Misdeals #1 rule ... Once action begins a misdeal can't be called and no money/chips will be returned to a player whose hand is 'fouled'.
This one's pretty straight forward but as with most things in poker ... It depends .. GL
