i was just watching last weeks episode of the fox sports poker superstars invitational .... the last hand i watched was where doyle brunson eliminated barry greenstien .... doyle had [10♣] [J♣] and barry had [K♥] [J♥] ...... doyle called barry's all in which was 18,500 or 4,500 over the top of doyle raise of 14,000 ..... the flop was [A♥] [7♣] [3♥] .... turn was [10♦] ..... and then the camera moves off the table and fox shows that the river was [7♣]


my question is this:

shouldn't there only be one [7♣] in the average deck of cards?
i understand that the river was most likey [7♠] but still ... shouldn't someone at fox catch this error before the show airs?
