The Us reached last season's Leagyue Two play-off semi-finals but Bradford were comfortably the better team at Valley Parade.
Stuart McCall's team moved the ball around well but were unable to break the stalemate in a 0-0 draw.
Here, chief football writer Stuart Rayner assesses how the Bantams players performed.
Richard O'Donnell – not over-worked, but an important first-half save from Kwarme Poku 7
Anthony O'Connor – did a good Chris Basham impression getting forward from the back three in the first half, but Courtney Senior's pace caused him problems late on 7
Paudie O'Connor – not overly troubled with numbers always on his side 6
Reece Staunton – like Anthony O'Connor, he got forward well and Clayton Donaldson ought to have won it with his 88th-minute delivery 7
Elliot Watt – steady holding the midfield 6
Dylan Mottley-Henry – right wing-back was at the heart of much that was good about the Bantams in the first half 7
Billy Clarke – linked well with the players on Bradford's right-hand side 7
Callum Cooke – had plenty of time to think about a volley, but hit it wide 6
Connor Wood – got into good positions but his crosses did not find their target often enough 6
Kurtis Guthrie – played with confidence but could not find the finish 6
Lee Novak – denied early on by Gerken and Eastman 6.
Ismail (for Mottley-Henry, 72) – topped up the energy levels 5
Donaldson (for Guthrie, 72) – lifted his side but missed a glorious late headed chance under pressure from Dean Gerken 6
Pritchard (for Cooke, 77) – Gerken saved his well-struck shot 6.
Not used: Longridge, Richards-Everton, Hornby, French.
