Harrison moves to Chesterfield
Harrison has put pen to paper on an 18-month contract with the Spireites after falling out of favour since Paul Buckle’s arrival as manager at the League Two club.
The 27-year-old has scored seven goals in 27 appearances this season after finding the back of the net 15 times last term – including against Chesterfield.
Blues boss Paul Cook told the club’s official website: “We have been monitoring Byron closely for some time and we believe he has the necessary attributes to be a valuable addition to our squad.”
Harrison, previously with AFC Wimbledon and Stevenage, will not be able to make his debut until Saturday when Doncaster visit the Proact Stadium.
