Birmingham City are allowing Sone Aluko to remain on-loan with Aberdeen for the rest of this season.
Brum boss Alex McLeish said: "As regards Sone Aluko, I spoke to Jimmy Calderwood about Aluko and have agreed he can stay at Aberdeen. He is doing all right. Hopefully it will toughen him up a wee bit.
"Jimmy has said he has done well and he's brave enough, although slightly built. We will get a word as to what the length of term the loan can be or must be."
