Nigel Worthington may be forced to look for more temporary reinforcements after Charlton recalled Kevin Lisbie from his month-long loan deal.
The Jamaican international was due to return to London on Friday after scoring once in six appearances for the Canaries, although injuries to fellow strikers Dean Ashton, Leon McKenzie and Peter Thorne had meant that City were keen to extend his spell.
An injury to Addicks forward Shaun Bartlett on international duty with South Africa has caused Alan Curbishley to end 26-year-old Lisbie's stay in Norfolk, having said all along that the move was only intended to help the forward, who has been absent for long periods of the last year, gain fitness.
Assistant manager Doug Livermore expressed his thanks to Lisbie and Charlton but must now be hoping that Ashton, who has been troubled by a head injury, will recover over the international break and be in contention to face Millwall alongside Paul McVeigh and Darren Huckerby.
McKenzie remains sidelined for several weeks after complications with his ankle injury, while defender Jason Shackell is still waiting to learn how long he wil be out after being stretchered off in Monday's reserve win over Watford. X-rays ruled out a fracture, but it has been confirmed that the young centre back, recently linked with a move to Barnsley after losing his place to Calum Davenport, has damaged ankle ligaments.
