City boss Phil Parkinson says it is too early to work out the exact nature of the injury picked up by Jon McLaughlin towards the end of Tuesday's victory over Morecambe
McLaughlin was forced off two minutes before the end of normal time after appearing to damage his hip while making an important save from former Bantams loanee Kevin Ellison.
It is hoped the problem isn't too serious but Parkinson would be more than happy to throw Matt Duke back in between the sticks for Saturday's match at Oxford United should McLaughlin be ruled out.
Parkinson said: "Jon's damaged his side - we're not too sure how bad that is at this stage. We'll obviously have to get him checked out with Matt (Barras - City's Head Physio)
"Dukey's (Matt Duke) come on and done fine though, we'd have no problems if he were to be involved on Saturday (at Oxford United).
"I must actually give a special mention to Dukey. He started the season really well but I just took the decision to bring Jon in at Accrington because I felt he was looking really sharp.
"He took that decision like a man. He has trained like a demon in training every day. That is credit to him and the sort of attitude we need from all of the lads who find themselves out of the team at the moment."
