Expert Gary Neville is to be referred to the Attorney General over a social media post he made during the domestic violence trial of former Manchester United team-mate Ryan Giggs.
The judge in the case, Hilary Manley, has called it a possible case of contempt of court.
The jury at Giggs’ trial was released on Wednesday after no verdict was reached on any of the three charges.
Giggs denied headbutting ex-partner Kate Greville, 38, in a row at home.
Giggs who resigned as Wales manager in June also denied a charge of coercive or controlling behavior against Ms Greville and denied assaulting Ms Greville’s sister Emma, 26.
The judge said the hearing would not be resumed until June 5, 2023 at the earliest.
Neville’s agent Di Law said the Daily Mail that the 47-year-old Sky Sports pundit was “absolutely adamant” that the post related to the Glazer family’s ownership of Manchester United and not the Giggs trial.
The disregard for courts law prohibits the posting of information that poses a “significant risk” of seriously undermining a process — including on social media. It is a criminal offense punishable by a fine or up to two years in prison.
The judge referred to Neville’s post on Wednesday.
Judge Manley said: “Given that the author is a high public profile individual and his social media account has 1.5 million followers, this could be viewed as an attempt to influence ongoing criminal proceedings and could constitute a disregard for the law represent court.
“Accordingly, I am referring the matter to the Attorney General’s Office for consideration of possible prosecution.”
A spokeswoman for the attorney general’s office said: “Contempt of court is a serious matter and the attorney general’s office will carefully review any allegations brought to its attention. We haven’t received a transfer yet.”
BBC Sport have reached out to Neville, 47, for comment.
During the trial, the prosecution attorney said he was made aware of a social media post “by a member of the public who has a direct connection to this case.”
He added: “This may be a matter that requires immediate action as far as that person is concerned.”
The lawyer defending Giggs, Chris Daw QC, wanted to make it “crystal clear” that the accused had nothing to do with the Instagram post.
Judge Manley allowed the trial to proceed after deliberations as there was no indication that a jury member had seen the post.
The former Manchester United footballer was in court for four weeks. The prosecution has one week to decide whether to open a retrial.
