Birmingham City's preparations for the new season have taken a turn for the worse after it was revealed that Martin Taylor faces up to three months on the sidelines.
The defender had to be taken off on a stretcher during the recent friendly at Nottingham Forest and scans have shown severe ankle ligament damage.
Blues boss Alex McLeish confirmed: "Tiny suffered a bad twist of the ankle. It will keep him out for a considerable period of time.
"So we've lost him as well as others and it has made centre-half problematic for us.
"Franck Queudrue came in for his first game last night, at centre-half, and you could see he was extremely rusty. We're definitely short in that department but it's just down to lady luck."
Meanwhile, McLeish is unsure whether Arsenal defender Armand Traore is coming to St Andrew's on a season-long loan.
The former Rangers and Scotland boss added: "I really don't know, I'm waiting on Arsenal. Arsene Wenger has obviously got one or two problems himself.
"I still have to discover whether he'll sanction him coming out. If not, then we'll maybe have to do something else.
"I think Traore has appeared in the last two games for Arsenal, so of course he wants to play for them first. I don't hold that against him in any way.
"We'll just have to watch this space because it's a problem position for us. There are one or two things we're contemplating, other targets we're considering. We have to have a plan B."
