World Rugby chief Sir Bill Beaumont has been accused of presiding over the 'destruction' of the sport amid various law changes.
Former Wales captain Paul Thorburn insists World Rugby chairman Beaumont should be ousted for overseeing the changes that he believes have made rugby union an even more dangerous sport.
The welfare and safety of players has become a prevalent issue in recent years, with a series of ex-international stars speaking out on the damaging effects of the brutality of the modern game.
And the World Rugby governing body have introduced laws in a bid to make the game safer at a time where players are more physically imposing and powerful than ever before.
But a large group of formers players who are suffering from diagnoses such a dementia and depression as a direct result of brain damage from their rugby career are plotting legal action against rugby's authorities.
And Thorburn, famous for holding the record for the longest ever place kick during his own playing days, believes former England skipper Beaumont has allowed rugby to be destroyed since being elected into his role in 2016.
"The laws of the game that have been changed over the last 15, 20 years have made the game… in effect rugby league with 15 players," Thorburn told BBC Radio Wales Breakfast. "There's no rucks. There's no mauls. The tackle laws, the line-out laws."
New Welsh Rugby Union chairman Ieuan Evans has a plethora of problems in his in tray, including the future of under-fire head coach Wayne Pivac. But Thorburn believes Evans must prioritise making a no confidence motion against Beaumount for the sake of the sport.
"He [Evans] needs to put forward a motion of no confidence in the chairman of World Rugby, Bill Beaumont, who has overseen the destruction of what has been a fabulous game with the changes of the laws over the last 10-15 years that have made it a game that really is not acceptable any more," Thorburn added.
"They've made it more dangerous and the evidence is there and it'll be interesting to see what happens with this case that's being put forward.
"If the players with head injuries win that (legal) case then the game is gone, so that would be Ieuan Evans', his and the Welsh Rugby Union's priorities are to bring some of these things to the top of the table."
