Birmingham midfielder Alex Hleb is sweating over whether he will be fit for the Carling Cup final after suffering a knee injury during the comfortable 3-0 home win over Sheffield Wednesday in the FA Cup.
Hleb left St. Andrew's on crutches after being on the receiving end of a mis-timed challenged from Owls defender James O'Connor. The former Arsenal player will have a scan in the next 24 hours which will determine whether he can recover in time to face the Gunners at Wembley next weekend.
Blues boss Alex McLeish said: "The latest is Alex is limping heavily. He will have a scan hopefully over the next 24 hours.
"We presume we can get something done on Sunday and we will know after that if there is any damage. It is his knee. We don't believe there is any cruciate problems but he got a fair rattle. The guy was very late in the tackle.
"He is a great player and we still believe he will make an impact for us at some stage this season and, hopefully, he will be okay for the final."
McLeish admitted he also substituted key defender Roger Johnson over fears he would be sent off and so banned for the final after he had collected a yellow card.
