The 2019–20 season got off to a poor start for Boro, with two wins, six draws, and four defeats seeing the Seadogs languishing in 15th position after twelve matches with twelve points. Unusually, they drew their first seven competitive home matches of the season, before finally recording a home win on 15 October. An FA Cup 1st Qualifying Round replay win against Marske United (mirroring the 2017–18 season) set up an attractive 2nd Qualifying Round tie away at National League North club Southport. However, Boro's cup run ended there in abrupt fashion, with Southport running out 5-2 winners. The disappointing run of results continued and manager John Deacey eventually left the club by mutual consent on 24 November and was replaced by Darren Kelly, who made an immediate impact, winning his first three league games in charge. On 25 March 2020, due to the worldwide Coronavirus pandemic, and following a suspension of football, the Northern Premier League season was declared null and void, and all records were expunged.
