A supporter who received urgent medical attention during today's game is responding well to treatment.
The match was stopped for just over 30 minutes in the first half to allow an air ambulance to land on the pitch and take the man away.
A club spokesman said: "A supporter was taken ill and emergency treatment was administered by St John Ambulance and East Midlands Ambulance Service personnel, with the crowd doctor also in attendance.
"The decision was then taken to stop the match to allow an air ambulance to land on the pitch. The person was taken away by helicopter to a hospital in Derby, where he has responded well to treatment.
"We would like to place on record our thanks to the staff from St John Ambulance, East Midlands Ambulance Service and the the air ambulance, together with the crowd doctor and matchday stewards, for their efforts.
"We send our very best wishes to the patient and hope that he makes a full recovery."
