Looks like a foul to me – puzzled with Cook saying that he (the ref) had all the other officials telling him it was a foul though.
No 4th official would ever try to come in on a decision from that far away. Same for the asst on Cook’s side too. Doubt that they would also have tried to drop the ref in it like that either.
It may have been that Cook asked em & they said they thought it might have been a foul from thei angle but the ref was in the better place to make any decision
