Home club Fleetwood Town confirmed the drone was not recognised, prompting referee Michael Salisbury to suspend play to consult with both team managers and the ground safety officer.
In the eighth minute of the match, referee Salisbury took the precaution of calling the players off the pitch for their safety.
The drone subsequently flew away from the stadium sky, enabling the match to safely resume after the brief delay.
Fleetwood then took a shock lead through Aaron Loupalo-Bi in the 21st minute.
