Birmingham have admitted the St Andrew's pitch will have to be dug up and relaid yet again in the summer.
Manager Steve Bruce said: "A lot has been said and written about the pitch and it is a disaster area for us.
"We've done everything we possibly can as a club to make sure it is right - but we are struggling.
"It will have to be relaid in the summer. It is a shame because only a couple of years ago it was the best pitch in the league."
