On-loan Macclesfield player Dan Gray will be able to play for the Silkmen against parent club Chesterfield on Saturday.
The versatile 21-year-old joined Macc from the Spireites in January and has made 17 appearances, including 16 starts.
Blues boss John Sheridan has no problem allowing him to play against his parent club in this weekend's League Two clash at the B2net Stadium.
He said: "Dan is available to play. He's gone there, (Macclesfield manager) Gary Simpson took him there and he's been playing.
"He's getting games under his belt which is why he went there, so it won't be a problem if he plays."
