Influential duo Andrew Davies and Kyel Reid are both doubtful for City's Yorkshire derby with Rotherham United this coming Tuesday after the pair both suffered injury woe at Chesterfield this Saturday.
Davies was forced to give up his place in City's starting line up to Michael Nelson after an old calf issue flared up in the warm up, while Reid was forced off at half time during the match itself after tweaking his groin.
Given the short space of time between the Chesterfield and Rotherham matches for City, any relatively serious injury would seriously rule either one of them out of action against Steve Evans' Millers.
With the pair being assessed further this Sunday though, more should be known about both Reid and Davies' fitness at the start of next week.
Bantams boss Phil Parkinson said: "Davo (Andrew Davies) has a bit of a problem with his calf where he gets a bit of spasm in there from an issue relating to his back.
"It was just tightening up a bit in the warm up but hopefully it is not a major problem.
"Reidy's (Kyel Reid) groin was tightening up as well so we had to bring him off.
"I was asked the question only the other day about how lucky we had been with injuries recently - probably a lesson not to tempt fate.
"We've haven't really been lucky as such with injuries - it has more been down to the good preparation work from our medical staff - but we have picked up a couple (injuries) today.
"We are going to have to assess those tomorrow (Sunday) because whoever we put out there on Tuesday (vs Rotherham United) has to be fit and ready to go."
