Burnley have apologised to Bradford after one of their supporters was ejected from Saturday's pre-season friendly at Valley Parade following an alleged racist incident.
The Premier League club have confirmed a visiting fan was ejected after a Bradford player reported the individual to the match officials, claiming he had been repeatedly racially abused.
The supporter has denied the allegations but other witnesses have backed up the complaints of the player involved.
Another fan left voluntarily and no arrests were made but, in a statement released on Sunday, Burnley offered an apology for the incident.
"We would like to offer our sincere apologies to the player involved and to Bradford City Football Club," it read.
"We will now be working with the police and Bradford City Football Club, who have CCTV footage of the incident, to hold a full investigation and identify the persons involved, when action will be taken accordingly."
On the pitch, Premier League new-boys Burnley recorded a convincing 4-1 victory, with Andre Gray grabbing an early brace.
