Blues’ last chance of silverware this season ended as they went down in extra-time in the Essex Senior League Shield semi-final.
Matt Waldron’s side were unlucky not to reach the final as they controlled the first half without taking advantage of the chances they created.
Swifts took command after the break and threatened to score on a few occasions but the hosts; defence remained firm.
In extra time both teams looked tired, but it was Heybridge who took advantage from a strike in the second half of the half hour to win the game.
The young Blues return to league action on Saturday when Grays Athletic are the visitors to the ProKit UK Stadium, kick-off 2.30pm.
