Following complaints from the player, the 30-year-old fan from Accrington was ejected from the ground and now Burnley have moved swiftly to ban the supporter from both home and away games indefinitely.
The statement read: "Burnley Football Club can confirm that a supporter has been given an indefinite club ban following an incident of racial abuse.
"A 30-year-old man from Accrington has been interviewed by Burnley FC officials regarding racial comments aimed at a Bradford City player during the Clarets' pre-season friendly at the Northern Commercials Stadium on Saturday, July 23, 2016.
"And as a result, and subject to the right to appeal, the supporter will no longer be able to attend any Burnley FC matches, including away games, with immediate effect. A second man who voluntarily left the stadium in connection with the incident will face no action.
"In closing, the club would like to reiterate that we have a zero tolerance approach to any such behaviour and strongly condemn discrimination of any type."
