The forward's joining on loan until the end of the season.
Chesterfield have signed striker Jack McKay on loan from Cardiff City, subject to receiving international clearance.
McKay, who will spend the rest of the season at the Proact, said: "I'm a hard-working striker and I can't wait to get started."
The 22-year-old started his career at Doncaster Rovers. After making a handful of appearances for the South Yorkshire club, he joined Leeds United.
While at Leeds, McKay had a spell on loan at Airdrie before moving to Cardiff a year ago following an extended trial.
