NRL admits Roosters' winning try should not have stood

Updated: 

Michael Gordon's match-winning try for Sydney Roosters against Penrith Panthers should have been denied by the officials, NRL referees boss Tony Archer said.

The Panthers were on course for victory at Pepper Stadium until Latrell Mitchell passed to Daniel Tupou on the left, whose grubber inside has hacked on by Gordon to cross in the 73rd minute.

However, Mitchell's offload went forward and was not spotted by the touch judge, with Archer acknowledging the play should not have stood.

"From the vision you can see that the touch judge is in good position to rule on the pass," said Archer in a statement carried by Penrith's official website.

"After reviewing all the available angles and slowing the play up, I have determined that the pass is forward.

"It's my expectation that the referees should have ruled that way."

Sydney consequently earned their third successive victory to remain joint-top of the ladder with Melbourne Storm.
