Phil Parkinson could appeal Andrew Davies' dismissal after celebrating his first win as Bradford boss with a 1-0 victory over Torquay.
Davies, who joined Bradford on loan from Stoke a fortnight ago, was shown the red card by Hull referee Carl Boyeson following a 24th-minute challenge on Gulls midfielder Danny Stevens.
However, former Hull striker Craig Fagan scored in the 38th minute to secure a 1-0 victory - his first goal in his third league match for the Bantams.
Parkinson said: "I would have been disappointed if it had been a yellow card, but now he will miss three games because he has been shown a red card.
"We need to have a look at it. I will speak to the chairmen and make a decision about an appeal. I had thought it was a bad decision, I am convinced the referee has got it wrong.
"You've got to be able to distinguish between a tackle with raised studs which injures a player and one which has won the ball. Referees are too quick to send players off. No-one goes out of his way to injure another player, although occasionally you might get a mistimed tackle."
