Andre Gray scored twice in the first half and would have preferred to be thanking his fans for their support ahead of their return to the Premier League.
Instead he took to social media and slammed two fans who appeared to ruin it for the rest.
"Well done to the two racist Burnley fans," he posted with an ironic thumbs up emoji. "Still live in the stone ages I see! Ignorant prats."
It's understood the 'fans' were directing their abuse towards a Bantams player which angered Gray.
The Clarets won the game 4-1.
