Birmingham defenders Franck Queudrue and Liam Ridgewell are available after suspension for the home Barclays Premier League clash with Everton.
Queudrue has served a one-game ban for his sending-off against Manchester City while Ridgewell completed a two-match suspension for incurring 10 bookings this season.
But skipper Damien Johnson is beginning a three-match ban for his red card at Wigan last weekend - City's third sending-off in the last seven games.
Blues boss Alex McLeish will check on the fitness of creative duo James McFadden (knee) and Olivier Kapo (hamstring) before finalising his side.
Mikel Arteta is a major doubt while Leon Osman has picked up a hip injury in training and is also a concern.
Arteta came off during last weekend's win over Derby with abdominal muscle pains, and has not trained this week.
If Osman is ruled out, Everton will find themselves seriously short of midfield cover.
Full-back Tony Hibbert (hip) and midfielder Steven Pienaar (knee) have also been under treatment this week and boss David Moyes will make a late decision on the pair.
