Jamaican international Donovan Ricketts is expected to play his first game of the season between the posts.
Midfielder Lee Crooks has not recovered from a groin strain. Defender Darren Holloway is doubtful and may not make it either.
Boss Colin Todd will be aiming for the double over play-off contenders Brentford. Last November, the Bantams bagged the points with a 2-1 win at Griffin Park.
City squad (probable): Ricketts, Holloway, Wetherall, Bower, Tierney, Schumacher, Bridge-Wilkinson, Emanuel, Morrison, Cooke, Windass, Henderson, Swift, Muirhead, Forrest, Bentham.
