Friday afternoon's U23s friendly against Norwich City at Playford Road will be played behind closed doors, the club has announced.
The Blues' U23s aren't in Professional Development League Two South action until a week on Monday when they face Coventry City at their Alan Higgs Centre training ground (1pm).
Meanwhile, free agent former Blues central defender Tommy Smith, who has been training with the U23s, has been linked with Wigan Athletic and Portsmouth.
Town boss Paul Lambert has repeatedly ruled out a return for the 29-year-old, who left the Colorado Rapids late last year.
Elsewhere, Bristol City midfielder Sammie Szmodics, who was claimed to be interesting the Blues earlier in the month, has joined Peterborough on loan.
