The Pilgrims will face Martyn Bunce's Boston Town (kick-off 3.00pm) in their first pre-season outing - at the end of their first week back in training.
Manager Ian Culverhouse is poised to field his new signings in the pre-season curtain-raiser, which is accessible via cash only - priced £7 for adults and £5 for concessions on the gate at Tattershall Road.
United's brand-new purple, navy and green away shirt will make its debut on Saturday.
The shirt is now on sale both in-person at the Jakemans Community Stadium and online here.
