New Cardiff City signing Jack Simpson is still not ready to start for his new club, meaning the options to replace Cedric Kipre for Wednesday night's game against West Brom appear to have narrowed significantly.
The centre-back joined on a permanent deal from Rangers last week, however Morison said last week that he was not ready to play a full 90 minutes.
He was named on the bench against Birmingham City at the weekend, though, which might have pointed to his fitness levels being higher than initially anticipated. However, Morison halted that train of thought.
