A really tough game this early in the competition. The last time AFC Fylde came to Boston (22nd April 2017) they won 3-0 and a couple of weeks ago Boston lost 2-1 at Fylde in the National League North.
My Computer has this one down as A Draw so I'm going for:
Boston United 1-1 AFC Fylde (28)
As usual for cup games it's predicting the score at the end of normal time.
