Sawtry star Chris Down is not expected to play again this season after suffering another on-field collpase.
Down fell ill during a Peterborough Premier Division match against Riverside last Saturday.
An ambulance was called and the match was abandoned midway through the second-half with Riverside leading 3-1.
An ambulance also had to be called to treat Down in a Premier Division game at Pinchbeck in November.
He lost consciousness on that occasion.
“This time it wasn’t so bad,” Sawtry manager Jason Bohonis stated.
“But it’s still a worry to see a player go down on the pitch when no other player is near him and we took the sensible option of calling for the ambulance and calling the game off.
“I’ve spoken to Chris since and he is fine, but he has now been referred to a cardiologist which must be a good thing for his sake.
“I can’t speak for Chris about the rest of his career, but I doubt that he will play for us again this season.
“The priority must be to make him better.”
Oakham United’s grip on the Premier Division title became firmer at the weekend as they pipped lowly Holbeach Reserves 2-1, while Stilton were losing 3-1 at Coates.
Coates are second in the table, four points behind Oakham, but Stilton would have finished first if they had won all their remaining games.
Stilton took the lead through James Nespoli, but two goals from Matt Heron and another from Joe Butterworth gave Coates the win.
Stilton are at Langtoft on Saturday
Oakham were in action against Uppingham last night.

Netherton won the President’s Shield last season after a mammoth penalty shoot out with King’s Lynn Reserves.
