A disappointing 4-0 home defeat to league leaders Farsley Celtic last weekend meant that the Gingerbreads would have to wait another week to confirm their status in the EVO-STIK Northern Premier League.
The defeat was the first loss in four games for Paul Rawden's side and leaves Grantham in 15th place - needing just one more point to confirm another year in the division.
Home side Scarborough are in the play-off race and know that only a win will do for John Deacey's men as they sit in seventh place and remain six points off fifth placed Gainsborough Trinity.
The Seadogs have struggled for form as of late - losing three of their last five games, including a 2-0 defeat away at promotion rivals Warrington Town last weekend in which new manager Deacey only took charge for the second time following previous manager Steve Kittrick's departure.
Grantham will be wary of the two danger men for the home side in the form of their frontmen - James Walshaw and Michael Coulson. Between the two of them, Walshaw and Coulson have netted 36 times in the league - with Walshaw the outright joint top goal scorer in the league on 21 goals this season.
The Gingerbreads can take confidence into the game knowing that they have already taken three points off the home side this season, after a late Jack McGovern goal eight minutes from time was enough to secure a 1-0 win during the August Bank Holiday weekend.
Grantham boss Rawden said his side can't afford to make the same mistakes as they look to get back to winning ways: "Last weekend wasn't good enough and so far away from the high standard we set ourselves.
"We have to be able to do the basics well this weekend as well as communicating with each other and helping each other out.
"Both sides have something to play for. They're chasing the play-offs and we still need at least a point to secure safety, but we will go there with the intentions of getting three points and three points only.
"We want to end the season as well as we can and that is going to start on Saturday by playing good football and getting the result we want."
Kern Miller was fit enough to start on the bench in last weekend's defeat against Farsley Celtic and should be fit enough to be in contention for a return to the starting 11 on Saturday.
The rest of the squad remains fit for selection.
