Bradford's home Sky Bet League One game against Bristol Rovers was temporarily delayed due to a drone circling over Valley Parade.
Referee Andy Haines halted play in the 65th minute with the game goalless and led the players from the pitch for their own safety as the drone hovered over the stadium, now known as Northern Commercials Stadium.
Bradford's said on the club's official Twitter side: "The game has been paused for the time being. A drone has been spotted hovering in the air above the pitch."
Haines brought the players back out after a three-minute delay and the match resumed.
