Tendayi Darikwa made his return from a month-long absence with a double hernia as a late substitute during the 1-0 defeat at Cheltenham on Tuesday night, and the highly-rated winger is expected to be involved again on Saturday.
Cook told reporters: "This is his first training week and he's come through that 10 minutes at Cheltenham.
"The likelihood is that he'll be on the bench again to start with on Saturday, come on, influence the game and then he's good to go.
"We're doing well in terms of bodies and numbers. We've got good selection, people to pick from, but we just need those goals."
The Spireites have scored just one goal in their last five npower League Two matches.
