Barnsley footballer Iain Hume was discharged from hospital on Wednesday as the row over his injury escalated.
The 25-year-old, who suffered a fractured skull in a challenge by Sheffield United's Chris Morgan, was re-admitted to hospital on Monday with an infection but is now well enough to continue his recovery at home.
While receiving this welcome news, Barnsley will not let the matter lie and have accused the Football Association of "big-club bias" after the ruling body decided on Tuesday that it will take no further action against Morgan.
The Championship club, who are considering legal action, believe the FA would have acted differently if a big-name player such as Cristiano Ronaldo had been injured.
Manager Simon Davey told The Star: "I am angry and disappointed. I think that they've let down Iain Hume badly and let down Barnsley Football Club.
"I think that had it been Cristiano Ronaldo, Alex Ferguson and Manchester United, the decision they gave would have been different."
Barnsley owner Patrick Cryne added: "The two people who should have been punished have got away with it. Chris Morgan is still playing football and Andy D'Urso is still refereeing.
"It has not ended for Iain Hume, he has suffered a serious injury which is career-threatening and was life-threatening.
"He and his advisers need to decide their next action. Barnsley Football Club has supported Iain throughout this and will continue to do so."
