A defeat on Good Friday and other results not going their way has sealed their fate.
Bradford City have now officially been relegated from League One, and will play their football in League Two next season.
On Good Friday, the Bantams lost 2 nil away at Coventry City.
The defeat, along with other results elsewhere, means Bradford are now ten points from safety, with only nine points left to play for.
After their lunchtime kick-off, the Bantams had a nervous wait to see if there was any hope of a reprieve, but Rochdale's win over Wycombe and Scunthorpe's goalless draw with Blackpool sealed their fate.
Bradford knew they needed either a win or draw in their game against Coventry, but when defender Nathaniel Knight-Percival was sent off just before half time, they realised it would be a tall order.
The Bantams' recently-appointed boss Gary Bowyer got off to a good start with a win in his first game in charge, but their recent form has been disappointing, with losses in their last seven games.
The relegation brings an end to Bradford City's six-season run in the third tier of English football.
Bradford City manager Gary Bowyer said:
“It is obviously very tough to take for everyone connected to the club.
“We started the game well, and had good chances early on, but Coventry scored from their first real attack.
“It was poor defending from us and we weren’t clinical enough in front of goal. Those instances pretty much sum up our season.
“We haven’t been good enough in either penalty box and we are where we are.
“It is not nice for the supporters, who are so proud of their club, but we have to conduct ourselves in a professional manner until the end of the season.
“After that we have a big task on our hands, which is already being prepared for.”
