Fylde 25, Doncaster Knights 17
Fylde produced a superb performance to beat the league leaders and clear promotion favourites.
The home side thoroughly deserved their win with tries by Steve McGinnis, Tom Burtonwood and Warren Spragg against 14-man Doncaster, who had number eight Adam Kettle sent off in the first half.
Fylde led 22-3 at half-time and though they only added three points in the second period, they were value for more tries.
Coach Mark Nelson said: “It was the best performance and best result of the season.
