Andy Myers will find out over the weekend if his season is over.
City's ultra-consistent defender is due to have a scan on the injured hamstring he suffered in last night's 2-0 loss to new leaders Manchester City.
Myers was stretchered off just before half-time after collapsing in agony following a run out of defence. And the Bantams will be holding their breath they don't lose yet another centre-half on a sicklist that already includes David Wetherall, Peter Atherton and Robert Molenaar.
He said: "I don't know the extent of the damage but I don't think it's torn, hopefully it's just a strain.
"I got knocked and as I tried to keep my balance I just felt it. I fell on the floor and knew straight away something was wrong.
"It feels better than when I did my last one so I'm hoping it's not too serious. The last thing I can afford is a long injury, we're down to the bare bones as it is especially in defence.
"Fingers crossed but I won't really know how bad it is until we get the results from the scan."
Nicky Law fears he could be without the defender for six to eight weeks - which would rule him out for the remaining eight games of the campaign.
He said: "I think that would be the season over before he's got time to get it right. That's obviously a big blow.
"I thought Andy did really well and he has done since my arrival. And if he was on the pitch I don't think they'd have got their first goal."
City's third defeat in six days leaves them teetering on the brink of the relegation dogfight, although last night's performance was much improved on the losses to Sheffield Wednesday and Stockport.
They will be watching other results anxiously before the next game at home to Birmingham on Tuesday.
Law, still being linked with the vacancy at Hull, has targeted 50 points for survival. He added: "We still need those few points desperately. But if the lads go out and play like that again then I'm sure they will get something out of the Birmingham game.
"They are a strong side but not in the same street as Man City. But we can't just sit back on one performance, we've got to put that effort in again if we want to turn things round."
