John Brain has called on the International Rugby Board (IRB) to change the regulations governing front-row replacements after his Worcester side had their chances of beating Saracens hampered by the enforcement of uncontested scrums.
Match referee Dave Pearson made the controversial decision an hour into Saturday's game at Sixways as the visitors ran out of front-row replacements at a time when Warriors were putting the Saracens' scrum under extreme pressure.
Justice was done in the end as Worcester ran out 25-24 winners, thanks to Tony Windo's last-minute try, but the hosts' cause was not helped by the fact that, for a quarter of the game, they could not capitalise on perhaps their main area of expertise.
There has been no suggestion that Saracens acted in an underhand manner - Brain has decided not to ask officials to look into the circumstances behind the injuries to Sarries' props Kevin Yates and Ben Broster - but he did stress that the whole area of uncontested scrums needs looking at.
"This really is an issue for Premier Rugby and the IRB," the Warriors' director of rugby said. "It needs to be addressed and given backing by the whole game.
"As the rules stand, they are open to abuse. I have made no issue or complaint in terms of what happened against Saracens but, if someone else decides to look at those circumstances, I would be happy to co-operate or comment."
Brain's solution would be to oblige clubs to name three specialist front-row replacements for each game - the current requirement is two.
"I would like to see eight replacements being named, including three specialist front rows, a loosehead, a hooker and a tighthead," he said.
"Then the issue would be less contentious and should uncontested scrums arise, they would be almost impossible to manufacture."
And he wants to see the issue dealt with quickly, before any more of his team's games are blighted by uncontested scrums - as he fears they might be with opponents unable to cope with Worcester's growing prowess at the set-piece.
Saracens, supposed to have one of the best scrummages in the top flight, were decimated and conceded numerous free-kicks, penalties and even a penalty try.
"The stronger our scrum gets, the more games we play will finish with uncontested scrums," said Brain. "That would be wrong because it is an important area of the game. Otherwise, we might as well be playing Rugby League."
As a product of the Kingsholm Forward Mill - Brain played his rugby in the second row for Gloucester - the importance he places on scrummaging is no surprise.
"You want a contest in all phases, supporters want that contest for 80 minutes. Even in international rugby the scrummage has a real role to play.
"It is the basic platform to play from and if you can establish dominance it gives you a big advantage.
"New Zealand have established themselves as the dominant team in the world again because their front five have given them the platform to do that."
Worcester's chances of doing something similar to London Wasps on Sunday will be diminished by Chris Horsman's twisted ankle.
The Warriors' tighthead came off at the end of last weekend's game is doubtful for the match in Wycombe but Brain expects him to be fit for the Powergen Cup match with Northampton Saints' the following week - should he decide to risk the rock on which much of Worcester's scrummaging supremacy is based.
