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." McLeish is also keeping his fingers crossed that Johnson's replacement, Curtis Davies, will have recovered from a knock to his lateral knee ligament. Midfielder Barry Ferguson is expected to be fit despite picking up a neck injury in the 1-1 draw at Ewood Park. Birmingham are 16th in the Premier League table, three points above the bottom three.
