Bantams boss Stuart McCall hasn't yet ruled out Colin Doyle for this Saturday's trip to Milton Keynes Dons - despite the fact the 'keeper is away on international duty.
Doyle is currently part of the Republic of Ireland national squad preparing for their forthcoming World Cup qualifiers with Moldova and Wales.
Ireland are due to host Moldova on Friday before playing away at Wales the following Monday.
City are looking into the possibility of flying Doyle back to England between the two fixtures to allow him to feature at Stadium MK.
Should that not be feasible, however, then shot-stopper Lukas Raeder is in line to make his Bantams debut after joining City at the end of August.
Fellow German goalkeeper Rouven Sattelmaier remains sidelined with a hamstring problem.
McCall said: "We have the opportunity of maybe getting Doyley back.
"If not, then Lukas, who has trained really well recently, will be involved.
"We will be taking George (Sykes-Kenworthy) with us as well, so we will have options."
Shay McCartan will miss out again at the weekend as he continues to recovery from a calf problem - an injury that has prevented him joining up with the Northern Ireland squad.
Timothee Dieng is back in contention, however, after making his return from injury during City's Development Squad friendly fixture with Manchester United in midweek.
The defensive-minded player could come back into the match-day eighteen for the trip to MK Dons with Adam Thompson away on international duty with Northern Ireland.
McCall added: "We had to keep Northern Ireland updated with regards Shay's progress.
"We had him scanned earlier and it revealed a small tear.
"It is obviously a blow for Shay that he hasn't been able to join up with their squad, especially with Northern Ireland doing so well recently, but he has been making progress recently with the physios.
"Hopefully he should be joining back in with the rest of the squad for training at the start of next week.
"Tim has been working really hard recently on his fitness with Shorty (Chris Short, fitness coach), and he cruised through 45 minutes on Tuesday.
"He will be added to the travelling party for this Saturday.
"He started the season well before his injury, so I'm sure he'll be keen to get back to that form as soon as possible."
