World Cup winner Lewis Moody believes the controversy surrounding George North's concussion may help protect players by highlighting the new safety protocols.
North was allowed to return to the field of play despite being knocked out during Wales' defeat to England the Six Nations opener on Friday.
The wing had passed a mandatory Head Injuries Assessment for a first-half incident, but his clash of heads with team mate Richard Hibbard in the second half was not spotted immediately.
For the Welsh medics to allow him to stay on really disappointed me.
The sport's governing body, World Rugby, has asked the Welsh Rugby Union for a full report on the assessment of North.
Moody, who himself suffered from multiple concussions during his England career, hopes lessons will be learned from the incident at the Millennium Stadium.
He said: "It has created a great talking point and now people are well aware of the new concussion protocols.
'Dangerous'
"From now on if there is any doubt the player should go off the pitch. In this instance he should never have been allowed to stay on it was far too dangerous.
"The reason we have all these new concussion protocols in place is to protect players. But we can see from George's performance in the second half, he was very pale, he didn't get into the game, he wasn't himself.
"For the Welsh medics to allow him to stay on really disappointed me."
The WRU says the second incident was not seen at the time but North was treated after studying video footage, and Moody believes video replays could play a part in protecting players in future.
"I can understand that sometimes you don't see it immediately when they are on the pitch.
"We had the advantage of TV reviews and it just makes such a big difference when you are trying to look after your players, and for moments like that to be allowed it just sets the wrong tone."
