Ravenhill sustained a shin injury in the midweek win over Wycombe and although X-rays later confirmed there is no fracture, he suffered heavy bruising and could miss out.
Nathan Doyle replaced Ravenhill on Tuesday night and is likely to return to the starting line-up if Ravenhill fails to make it.
Manager Phil Parkinson, who has no new injury or suspension worries, has been boosted by the availability of defender Carl McHugh, who has been allowed to join up with the Republic of Ireland Under-21s after the match.
Parkinson must decide whether to start with leading goalscorer Nahki Wells on the bench again, while fellow forward Alan Connell, defender Michael Nelson, McHugh, goalkeeper Matt Duke and midfielder Will Atkinson are all in contention as the Bantams chase back-to-back home wins in a bid to keep their outside play-off hopes alive.
