Paul Gallagher remains the only doubt - he has been out for four weeks following an ankle injury picked-up in the 1-1 draw against Barnsley - with the Scot set to return to full training only at the end of this week.
However, Richie Wellens (groin) and Michael Johnson (shoulder) both trained with the rest of the Leicester City first team today and are set to challenge for a starting berth in a highly competitive midfield. Andy King, sidelined over the weekend with a back complaint, did not appear for Wales but will be in contention for the Foxes, as will Jermaine Beckford who has shrugged-off a groin injury. Sven Goran Eriksson is confident that at least four of the five injured players will be competing to return to action with the Foxes on Sunday.
"They are all getting better and Wellens and Johnson have joined in full training," said the Leicester boss, "Then we have Beckford, Gallagher and King. I am pretty sure they might be available, all of them, for Birmingham. I hope they can train today or Thursday. If that is the case, they could be available. Gallagher has been out for a while so he is doubtful, but the other two have a good chance. King has a back problem, but it is not serious. The problem is you can't really move with a back injury, but he is improving."
Eriksson is keen to see his side build on recent successes in the league and, having gone four league games without conceding with his team in good form, altering his starting line up could be seen as a controversial move.
"It would be good to have them all back and have the problem of who to pick," added the Swede, "It's good news for us and will be some headache to have."
