Carey was forced off after 56 minutes of Saturday`s 2-0 home defeat to Leeds following a collision with Max Gradel which left him with substantial bleeding from his nose along with two facial cuts.
But fears of a fracture have now been allayed and the defender could be in line to face Leicester on Friday.
Manager Keith Millen told City`s official website: "It seems to be good news as far as Louis is concerned.
"The medics have checked him out and it`s not broken. There`s obviously some damage there but we hope to have him available for Leicester away on Friday."
