Quote: Conroy "
... Harrigan who said that the try was awarded as Farrah made a play at the ball and kicked it from Inglis' hands. The knock onto his forearm was unintentional and so play on.
Now whilst I agree with that, I've seen it a million and one times and I don't believe that Farrah makes a deliberate play at it.'"
I don't believe Farah made a play at the ball, I believe he tried to get his boot under the ball to stop it being touched down and that's exactly what happened.
When at that moment Inglis tried to ground the ball, it hit Farah's boot and did indeed hit Inglis' forearm and he did not play at the ball, so that part is correct, it would only be a knock on if had played at it, but you'll never see someone knock a ball on with their arm and it not be given as a knock on again. They've even abandoned applying the "played at" rule in the tackle, after a short experiment where some highly dubious dislodges were let go.
So technically a correct ruling, within the rules it's a try, but it shouldn't be.
