The threat of relegation still hangs over St Leonards following a 3-1 defeat at Langney Sports last night.
It was Saints' seventh successive loss and they may well need to win at high riding Grantham in their final game to be sure of safety.
They had a nightmare first half at Priory Lane, losing Craig Willard with an ankle injury in the 28th minute following a clumsy challenge from behind that earnt Matt Crabb a booking.
Mark Fox was also booked for dissent following the incident and ten minutes later received his marching orders for a crude tackle on Crabb.
Sports had got off to a storming start with John Westcott heading them into the lead from a Clinton More cross in the seventh minute.
St Leonards' ten men fought with great spirit in the second half and their hopes were raised when Danny Moody levelled from close range in the 65th minute following a Danny Fletcher corner.
But a minute later, a classic More chip over advancing keeper Rob Hall restored Langney's lead.
Substitute Andy Ducille sealed the game for Sports five minutes from time after fine work on the left by Westcott.
It was Langney's first victory over their Sussex rivals in senior football.
lCrawley avenged their Dr Martens League Cup final defeat against Worcester City at the Broadfield Stadium with a 1-0 win in the Premier division last night.
They could not have got off to a better start as a seventh minute free kick was headed on for Dean Wordsworth to bury past Danny McDonnell.
Andy Little pulled off a superb point-blank save from Mark Owen's 21st minute header to preserve Reds' lead while Andy Bradley saw his effort for Worcester disallowed for hand ball.
Mark Hynes could have extended Crawley's lead in the first half but after breaking through the Worcester's defence, he placed his shot the wrong side of the post.
Wordsworth was denied a second goal by City keeper McDonnell while Hynes vollyed wide and later saw McDonnell save well at his feet. Little denied Bradley a late equaliser for the visitors with another brave stop.
