NRL referees Ben Cummins and Gerard Sutton have been stood down from this weekend’s round of matches after inadvertently sin-binning the wrong player last weekend.Cummins and Sutton were held to account for a poor performance in Parramatta’s 22-8 win over South Sydney on Sunday, which reached its lowest ebb when Eels skipper Nathan Cayless was sin binned following a string of penalties in the second half.Replays showed that Daniel Mortimer and not Cayless had in fact committed the indiscretion when he stripped John Sutton of the ball.”Referees will continue to crack down on teams that continually breach the rules but it is clearly unacceptable for the wrong player to be sent to the sin-bin,” said referees boss Robert Finch, who backed the continued use of the sin-bin.”Referees are accountable for their performances and between the two of them this error should not have occurred.”It is now up to both Ben and Gerard to work their way back into the top grade, which I am sure they will do.”AAP
