Bradford manager Phil Parkinson bemoaned the dismissal of captain Michael Flynn as his side's poor run continued with a 2-0 defeat at Hereford.
Flynn saw red for a second bookable offence before Steve Leslie, on loan from Shrewsbury, slammed home a tremendous 35-yard free-kick in the 78th minute.
Midfielder Tom Barkhuizen scored Hereford's second with two minutes remaining to send Bradford back to Yorkshire pointless.
"The sending-off killed us. To get booked I was annoyed with - then to do the other foul when there was no need for it cost us the game," said Parkinson.
"Their second goal came when we were chasing the game, when we were trying to get back in there. Our two centre-halves played well and were unlucky to be on the losing side, but the sending off cost us.
"We didn't produce the football I know we can, but sometimes when you are away from home you don't get the chance to do that. But you want to make sure you get back on the coach with something. Our centre-halves dealt with everything and I can't fault them, but when we went down to 10 men we became disjointed."
