Notts County have completed the signing of goalkeeper Joe McDonnell on a deal until the end of the season.
The 25-year-old was most recently at AFC Wimbledon, where he worked with Neal Ardley and Neil Cox, and his arrival has paved the way for Ross Fitzsimons to return to Chesterfield on loan for the remainder of the campaign.
Cox said: “We had a very amicable chat with Ross this morning and he’s decided to move on.
“While we wanted Ross to stay and provide competition for our goalkeeping spot, the manager can’t guarantee anyone a starting role in the team.
“Ross wants to play as many games as he can and he feels Chesterfield will be the best place for him to do that. We wish him well.”
