Saltdean travel to Steyning tonight as they entertain Haywards Heath with a place in the final at stake.
Both sides are familiar with each other, having already played each other twice in this domestic campaign.
Back in October, Heath ran out 3-0 winners on their own turf, whilst both teams claimed a share of the spoils last time out as they drew 1-1 just under three weeks ago.
With both sides still in the hunt for a promotion spot, they put league matters to one side this evening as they go head to head for a place in the final.
Steyning FC is the venue and it's a 19:30 Kick off.
