Phil Parkinson has revealed that Jon McLaughlin's side injury has been found to be nothing serious but that he will still need to prove his fitness ahead of City's trip to Oxford United this weekend.
McLaughlin was forced off towards the end of Tuesday's win over Morecambe after appearing to land awkwardly while making an important save to deny former Bantams loanee Kevin Ellison.
Parkinson says McLaughlin must be 100% fit to be in contention for a starting berth at the Kassam Stadium, meaning the Scottish shot-stopper will need to train fully ahead of City's journey south on Friday.
After replacing McLaughlin in the closing stages of the Morecambe win, Matt Duke is waiting in the wings to do so again against Oxford if needed.
Parkinson said: "Jon only has a slight injury. It's more of an impact injury than a strain. He says it feels a lot better today but obviously he has to be completely right to play.
"He has to be right to play because we have a very good replacement breathing down in his neck in the form of Matt Duke. Matt himself was unlucky to find himself out of the team recently.
"Jon will have to convince us tomorrow that he's 100% right to play."
