Birmingham are hopeful key defender Roger Johnson will be fit for this weekend's crucial home clash with Sunderland.
Johnson suffered concussion in the weekend draw at Blackburn and had to be taken off at half-time - much to his irritation.
Blues boss Alex McLeish insists he was right to replace the former Cardiff man and is confident he will be able to count on Johnson for the game against freefalling Sunderland.
He said: "I had to drag Roger off. You know how he never wants to stop playing. He was just saying `give me half-time', but I said `no chance'.
"He had a bit of a rant and a rave, as he does. But I told him there was no way I was going to compromise the health and safety of one of my most important players.
"The doctor felt there was concussion. Roger was a bit groggy but he will get over it. We don't think it's too severe and hopefully he will get over it for the weekend."
