Dover picked up a creditable draw at Weymouth in Saturday's televised National League game.
Andy Hessenthaler's Whites led through Koby Arthur's stunning strike but were pegged back before half-time and are 14 points from safety.
Dover made four changes from the team that shipped four goals before half-time at Eastleigh in midweek.
On-loan Keeper Adam Parkes made his first start while Junior Tiensia - signed on loan from Millwall until January ahead of kick-off - came into the side at left-back.
Skipper Sam Wood dropped to the bench so Ben Williamson took the captain's armband.
Whites were delayed en route to Weymouth but they made a quick start and were the better side in the opening 20 minutes.
Weymouth should have been reduced to 10 men after 18 minutes but the referee waved play on when Tyler Cordner clearly fouled Ben Williamson in the box - it would have been a red card and penalty had the referee ruled in Dover's favour.
Four minutes later the visitors were ahead when Koby Arthur was given time and space 25 yards from goal and he promptly found the bottom corner with a stunning right-foot strike.
Weymouth got into the game just before half-time and punished Dover for failing to track the run of Josh McQuoid, who finished off a move he started after going into the area unmarked and slotting beyond Parkes.
The hosts started the second half brightly, Henry Woods making a fine save before Brad Ash went close for Weymouth - the same player then denied by Parkes.
Dover looked a threat on the counter with their pace and Weymouth keeper Ross Fitzsimons had to be out smartly to deny Aaron Cosgrave from an acute angle.
Tiensia strode forward from left-back and shot narrowly wide from distance for the visitors with 17 minutes left before Arthur's shot on the turn was straight at Fitzsimons.
Although Weymouth had plenty of territorial advantage late on, they were unable to fashion out any clear-cut chances in the closing stages.
