Dover Athletic 0 Concord Rangers 1
Dover manager Chris Kinnear
Dover produced their worst performance of the season so far as they went down 1-0 to Skrill South new-boys Concord at Crabble.
Chris Kinnear's men failed to build on last Tuesday's win against rivals Ebbsfleet in front of less than 700 spectators - nearly 900 down on the gate in midweek.
The Canvey Island-based side claimed the points with a second-half goal from substitute Danny Spendlove.
Only on the pitch for 15 minutes, Spendlove made the breakthrough netting the 65th-minute winner, shrugging off his markers before shooting into the far corner.
Dover suffered an early scare when Jason Hallett headed against the Whites bar after only seven minutes, before home youngster Tom Murphy saw an effort saved by Jamie Butler at the other end.
Sean Raggett headed wide shortly after half-time, before Spendlove struck.
Murphy went close again with 15 minutes left, but was again denied by Butler.
