Fresh from Tuesday's 1-1 draw at Alfreton Town, the Pilgrims will be targeting a return to winning ways when they play host to Phil Parkinson's play-off chasing Robins.
United won 2-0 at Moss Lane earlier in the campaign and have the opportunity to complete their first league double of the season.
Boston boss Craig Elliott is poised to select from a predominantly unchanged squad, with defender Ben Middleton still sidelined.
The Robins are winless in their last four league encounters and have dropped from third to ninth in the process.
Altrincham's last visit to Boston culminated in a 1-0 victory in March 2017.
Saturday's match referee is Dean Watson, who last took charge of the Pilgrims in September 2017 against Darlington.
