Salford have expressed their disappointment that Danny Brough will not be punished for the tackle on Mason Caton-Brown which left the winger facing an injury absence of around 12 weeks.
Caton-Brown, who was playing in his first Super League match of the season, sustained a serious lower leg injury during Salford's Easter Monday clash with Huddersfield.
Although the tackle was cited, no further action was taken much to the annoyance of the Red Devils who are powerless to take the matter any further.
Head coach Ian Watson said: "We have asked the RFL to look over the incident again and have been told there's no case to answer.
"Lots of coaches have raised the issue of cannonball-type tackles and that they should be outlawed as they're extremely dangerous and this is what's happened here.
"We're disappointed that the tackle on Mason has been cited by the disciplinary but no further action has been taken.
"We're not happy about it but we've got our hands completely tied and nothing more can be done.
"It's disappointing as a young lad is now facing a long period on the sidelines at a time when he had a great opportunity to play first-team games."
And director of rugby Tim Sheens added: "While already being held by two other opposition players, Mason is hit with a forceful cannonball-style tackle to his lower legs.
"Our priority is to look after the welfare of our players and these type of reckless and careless tackles should carry serious consequences."
Salford will also be without Tommy Lee and Greg Johnson for around six weeks due to injuries.
