Sale Sharks director of rugby Steve Diamond has insisted the decision against Denny Solomona is worrying as the panel who made judgement had no evidence of wrongdoing by the two-time capped England winger.
Solomona was given a four-week ban after being found guilty of verbally abusing Jamie Shillock but Diamond stated that there was no witnesses or evidence to the incident on the pitch and that the decision goes against the values of rugby union.
"We accept the ban. We are disappointed with the result. I think it is a big changing point in rugby, where one man versus another, who do you believe?" Diamond told BT Sport.
"There was no evidence, no witnesses and the panel decided not to believe Denny [Solomona]. So I am worried about what happens in every game, not just at this level, but every club game, can it happen where somebody says to the referee that something has been said and no one's heard.
"People talk about the values of the game, but the values of the game rugby union, have also been that what goes on the field, to a certain extent, stays on the field. That has gone over that line now. We accept the decision, we are disappointed but we move on."
