St Leonards are facing up to life without their top scorer Carlton Chatelier.
The 27-year-old Londoner, who has hit 11 league and cup goals this season, has told boss Andy Thomson that he won't be available again this season because of personal reasons.
It's a big blow for the Dr Martens Eastern Division outfit whose fortunes appear to be on the up after encouraging results over Christmas.
Last Saturday they recorded their biggest win as a Dr Martens League club when Chatelier hit a hat-trick in the 8-2 demolition of Corby Town.
Then on Boxing Day Saints drew 0-0 at local rivals Hastings despite playing for the last 25 minutes with nine men after Adam Flanagan and assistant manager Keith Miles were both sent off.
That could have been Chatelier's last game for the club, although Thomson is hoping to persuade him to play on an occasional basis.
He said: "It's sad news. I'm hopeful he hasn't played his last game for us, but whatever decision he makes I will respect because he has done ever so well."
Mark Fox will probably replace Chatelier at Spalding tomorrow. On Monday Saints entertain Langney Sports.
Crawley boss Billy Smith is likely to name an unchanged side for the Premier Division clash with Worcester City at Broadfield Stadium.
Smith was pleased with the contribution of strikers Francis Vines and Mark Hynes in Boxing Day's goalless draw against fellow high-fliers Margate.
Reds are just three places and two points better off than their visitors tomorrow who have the best away record in the division, having won six times on the road.
Aussie midfielder David James is a major doubt for Hastings' home clash against Baldock in the Eastern Division.
James, who was playing only his second game for the club after brief trial spells with Barnet and Peterborough, suffered mild concussion and was left bleeding heavily after a challenge from St Leonards' Adam Flanagan in Tuesday's derby stalemate.
