Simon Davey has told BBC Hereford and Worcester about the freak injury to goalkeeper Dan Connor (library picture).
"We've had the results of scans but are waiting to see a consultant to see how severe it is," said the Hereford United manager.
"He did everything all week and got out of the car on Saturday night and something popped in his hip and he has been in hospital all week.
"He had an operation about three or four years ago in that area but since then he has played 70-odd games since then.
"He has had no problems whatsoever and has come through everything and not looked as though he has been carrying it at all in training.
"Speaking to consultants they say it can happen to anybody at any stage and sometimes it is just the way you get out of a car.
"Unfortunately that's what he did - he got out of the car in a strange way and something has popped."
Goalkeeping coach Russell Hoult is expected to be in the squad for the game at Burton on Saturday.
