What happens when everyone plays 7 stud till the end?

7 stud is played on this site at an 8 person table, yet there are not enough cards in the deck for everyone to play the full game, so what happens when all 8 players play until the river?

If that happens, a single seventh card is dealt face up as a community card. All players may use that card. So is 8 players with 6 cards in their hand plus 1 shared card to total 49 cards in play
