The winger had been expected to miss the remainder of the campaign with a torn hamstring that he suffered last month.
However, with Wolves in the relegation zone, Saunders has conceded that he is prepared to "risk" the 24-year-old.
"He can sprint and he'll be available for Saturday. We are rushing him back, so we will see how he trains tomorrow and Friday," the Express & Star quotes the Welshman as saying.
"Is it a risk? Yes. He's ahead of schedule but we've got no choice. We're short of goalscorers – somebody who can score out of nothing.
"If he smacks one in, or scores from a free kick, it might be just what we need. It's whether I start him or he goes on the bench, but he hasn't joined in with us yet."
Sako joined Wolves last summer from French outfit Saint-Etienne.
