Sako has been absent from the side for more than a month due to a hamstring tear which was first thought to rule the winger out for the rest of the season.
But defeat at Charlton last weekend returned Dean Saunders' men to the bottom three, and the Molineux boss is preparing himself for a final throw of the dice to see if his side can capture an invaluable three points.
Saunders told the Birmingham Mail: "We are obviously rushing him back.
"Is it a risk? Yes. We've got no choice. We are short of goalscorers, somebody who can score out of nothing.
"If he smacks one in it might be just what we need. He'll be in the squad on Saturday."
