Dover Athletic's Blue Square South promotion push is in danger of coming off the rails after relegation-threatened Worcester won 2-0 at Crabble on Tuesday night to complete an unlikely double over Andy Hessenthaler's side.

The visitors were worthy winners in the end, despite Dover having the better of the first half, and secured the win thanks to goals from Marc McGregor on 62 minutes and Rob Elvins five minutes from time.

The win left the Whites in eighth, four points off the playoff places, although some of the teams above them have played a game more.

In Ryman League Premier Division Dartford got back to winning ways with a 1-0 at Maidstone United.

Lee Burns smashed the winner from a Ryan Hayes cross after just 10 minutes to restore their lead at the top of the table to 11 points with four games in hand.

Maidstone have only scored once in four games and fell to 17th, just two places and four points outside the relegation zone.

Margate boosted their survival hopes with a 2-1 win over promotion-chasing Tooting and Mitcham - their first at Hartsdown Park since October 3.

New boss Iain O'Connell's first win in charge was secured by a 69th-minute winner from debutant striker Leroy Huggins, newly-acquired from VCD Athletic.

Sam Jones had opened the scoring for Gate before the visitors levelled before the break.

Gate remain eight points from safety and bottom of the table, with 12 games remaining.

Ryman League Division 1 South leaders Folkestone Invicta marched on with 11th 1-0 win of the season, this time against Eastbourne Town at Buzzlines Stadium.

A second-goal in as many games from new signing Brendon Cass on 51 minutes gave Invicta their 22nd win from 30 games, though nearest challengers Croydon Athletic overcame Whitstable Town 3-1 to stay a point behind Invicta with two games in hand.

Whitstable were 2-0 down before Dan Stubbs pulled one back on 57 minutes and remain third-bottom, but Ashford - who lie a place and three points below them - now have two games in hand.

Sittingbourne's push for a play-off place stuttered with a 3-2 defeat to Burgess Hill Town at Bourne Park.

Carl Dent cancelled out an early opener on 12 minutes but Hill had gone 3-1 ahead before Tom Bradbrook pulled one back in the final minute.

Seventh-placed Bourne are now five points off the top-five, but still have two games in hand on some of their rivals.
