National League North club Darlington are facing fines from the FA after pyrotechnics were thrown onto the pitch in two recent games.

Hitting out at the actions of 'reckless and irresponsible' fans, The board of directors at Blackwell Meadows have said pyrotechnics, which are usually smoke bombs, were thrown onto the pitch as the match officials and teams entered the pitch in games against Scunthorpe and Spennymoor Town.
"This is a dangerous and criminal act," the directors said in a statement, adding both cases have been reported to the FA by the match referee.
While they are waiting to hear from the FA, they said before Saturday's game at Spennymoor, fans ignored warnings.
"Two similar incidents in four days does not reflect well upon the club, and the FA is sure to take that into consideration," the statement said.
"We are likely to be heavily fined, and warned about our future conduct. If there is any repetition, then as well as a heavy fine, they could force us to play behind closed doors, as they did recently with Bury, or even deduct points.
"Whatever the punishment, it will affect our resources at a key stage of the season, and reflects badly upon the club.
"The reckless and irresponsible behaviour of one or two individuals threatens the momentum that the club has achieved in recent weeks. We would ask our true fans to identify these culprits before they derail our progress and to write to us in confidence on report@darlingtonfc.org."
With Darlington boosted by good results lately, including a 4-0 home win against high-flying Scunthorpe, they are now just one point from safety.
