Saturday's 3-0 defeat was also followed up with a 3-1 defeat away to Lancaster City on Tuesday - a result which saw the Gingerbreads slip to 4th in the table after Ashton United picked up a 1-0 win over Stafford Rangers on Tuesday night.
The Gingerbreads had previously been on a run of five successive wins before losing the two previous games and will be wanting to return to winning ways this weekend.
Home side Workington haven't had much more success in recent times, also losing their last two games, and three in their last five games. Tuesday night was the most recent defeat for the side, which saw them go down to a 2-1 defeat at home to Farsley Celtic. That result left Workington in 11th place with six games remaining.
The Gingerbreads have already faced Workington once this season in September where they managed to come from behind twice to win 3-2 thanks to a brace from Jordan Hempenstall and a last minute winner from Lee Shaw to take all three points.
Despite the Gingerbreads having to play Saturday without the suspended Kieran Preston, Grantham boss Adam Stevens is confident his side can bounce back this weekend: "The game was always going to be tough with or without Kieran and although it isn't ideal, we are confident we have an adequate replacement for him just like we do for Tom (Batchelor). There's not long left and every game is crucial and I know the lads want to make up for the past two results and we are confident of doing so."
As mentioned earlier, Kieran Preston and Tom Batchelor are both suspended for the game whilst Luke Shaw still remains out of contention through injury. Jordan Hempenstall and Zayn Hakeem are expected to return to the side after both being unavailable on Tuesday night. The rest of the squad is available.
