Wales defence coach Shaun Edwards has added his voice to a chorus of disapproval aimed at the Millennium Stadium boo-boys.
Fly-half Rhys Priestland will line up against Fiji tomorrow just a week after he was jeered when he replaced an injured Dan Biggar early in the second period during Wales' 33-28 loss to Australia.
The booing came from a small minority of home supporters, and their behaviour has subsequently been condemned by Wales head coach Warren Gatland and Priestland's squad colleagues.
And Edwards has now told those fans: "You boo one of us, you boo all of us."
The protest at Priestland has prompted an angry response from within the Wales camp, and Edwards hit back strongly.
"With Rhys Priestland, it is important to remember that most of the crowd is behind us, but you boo one of us, you boo all of us," Edwards said.
"If you boo Rhys Priestland, you boo myself, you boo Warren Gatland, you boo Leigh Halfpenny, you boo the Welsh jersey.
"Personally, I don't think that is on.
"Over the last number of years we have performed admirably as a Welsh nation, with only 20,000 players and three million people, we've tried to wear that Welsh shirt with a lot of pride.
"For someone to boo that shirt, to be honest, I am not very happy about it."
Priestland will be part of a much-changed Wales team from the Wallabies clash, but one that should still be good enough to win comfortably ahead of next week's Millennium Stadium appointment with world champions New Zealand.
