"Is Johnson in the frame?," McLeish has said.
"At the moment we still feel he can do some more training and get real sharpness although I think Damien is the type of guy who, when we give him the nod, will slot back in with no problem.
"I looked at Damien at Rangers when he was a kid at Blackburn. I tried to snatch him, but we couldn't do it.
"He is a valuable player. He is the type of player in a team that your team-mates appreciate.
"What I've got to be cautious of is he's had an injury and I want to make sure he is right.
"If we put him back in and he breaks down again, then we lose a valuable player and we also undo a lot of good work that the physios and fitness guys have done with Damien.
"It doesn't mean to say that he won't break down again, even when I decide that time is right, but I certainly want to give him every chance."
