Michael Appleton faces a squad crisis ahead of the weekend trip to Barnsley.
Greg Halford left Fratton Park on crutches after picking up a knee injury in last night’s 1-0 defeat to Ipswich. In addition, Liam Lawrence was substituted just before half-time with a calf problem.
They join David Norris and Luke Varney, who have already been ruled out of Saturday’s Oakwell clash, on the sidelines.
It leaves Appleton with just 15 fit first-team players at present.
And the Blues boss is seeking assistance from the Football League to solve the crippling squad shortage.
He said: ‘What we have got to be very careful of is to make sure we have enough players first and foremost to fulfil fixtures.
‘Luke Varney and David Norris are out and the possibility of Liam Lawrence and Greg Halford as well makes things very, very difficult.
‘So between ourselves, the directors and the administrators, we need to somehow have a look at the possibility of recruiting one or two players somehow.
‘Norris and Varney are not going to be back for Saturday. Lawrence and Halford are both pretty sore at the minute so it will be assessed over the next 48 hours.
‘It is going to test us right down to the bones.
‘I have heard nothing from the Football League at the minute.
‘But once the court hearing is heard on Friday regarding administration, I would like to think we can be in a position to be able to do something.’
