Blues top scorer Tom Lawrence will return to the squad for Saturday’s trip to Fulham, but midfielder Cole Skuse remains sidelined with the concussion he suffered during Saturday’s 1-1 draw with Birmingham.
Lawrence, who has scored 11 times during his loan spell from Leicester, has missed the last two games as well as Wales international duty with a groin problem.
"Tom Lawrence looks like he’s fine, he’s trained fully today and he’s looked in good shape, but Skusey won’t be available,” manager Mick McCarthy said.
"I just think he’s not been completely headache free, I think he has just been brutally honest and admitted to it. We can’t take that risk, it’s not on.
"Generally it is two weeks unless they’re completely clear. And we don’t want to take any risks, he’s been fantastic Skusey. Rule is he can’t play.”
With Jonathan Douglas, Teddy Bishop and Andre Dozzell all at his disposal, McCarthy says he’s well covered in central midfield.
"They’re fit and the lads who played the other night played very well,” he added. "We’ve got cover for Skusey. He’s been pretty much ever present unless he’s been injured, which is the case again. But we’re all right, we’ve got midfield players.”
