Following a goalless opening 45 minutes, the hosts were reduced to 10 men just before the hour mark as Joey Barton received his second yellow card of the contest.
Nancy's winner came in fortunate circumstances with 73 minutes on the clock when Andre Ayew put the ball into his own net from a corner.
