Jamie Arnold, aged 32, faced accusations of racially abusing Rio Ferdinand during a match between Manchester United and Wolves at Molineux in May 2021.
However, the jury at Wolverhampton Crown Court has been discharged after informing the judge that they were unable to reach a majority verdict.
As a result, the man accused of racially abusing Rio Ferdinand now faces the possibility of a retrial.
The jury has now been discharged and the Crown Prosecution Service has confirmed it will seek a retrial, possibly in November.
Mr Arnold denies causing racially aggravated harassment, alarm or distress.
Ferdinand gave evidence at the trial and it is thought likely he will again be called as a witness for the retrial.
Arnold, 32, was accused of racially abusing Ferdinand during Wolves’ game against Manchester United at Molineux in May 2021, at which the former England international was working as a pundit for BT Sport.
