The 19-year-old has made eight appearances for the struggling Blades this term but has not featured for the Sky Bet League One side since mid-September. He is set to be on the bench when the Spireites host Wycombe on Saturday.
"Going into the busy Christmas period, we must ensure that we've got good cover," Chesterfield manager Paul Cook told the club's official website.
"We're very grateful to Sheffield United for allowing us to borrow such a good young player, he gives us great cover on the left-hand side."
