Johnson a doubt for Blues
Birmingham will give a late fitness test to central defender Roger Johnson ahead of the home Barclays Premier League match against West Ham.
The former Cardiff player suffered an ankle injury during last weekend's goalless draw at Aston Villa and has been unable to train all week.
If Johnson is ruled out, Martin Jiranek is the obvious candidate to replace him providing he shakes off a thigh strain.
If Jiranek is also unfit, Liam Ridgewell would probably switch from left-back with Stuart Parnaby replacing him on the flank.
