Craig Elliott believes Saturday's FA Trophy tie with Chesterfield is '99 per cent' unlikely to go ahead, but admits he's not sure what that means for the contest.
The Spireites announced on Friday that the weekend's contest against Bromley had been postponed due to the squad isolating.
It is believed their 10-day period will also include the scheduled knockout match at the Jakemans Community Stadium.
"Nothing's confirmed yet," said Elliott. "I would imagine its 99 per cent sure we won't play on Saturday. I don't know what will happen after that.
“I imagine that will go to a midweek game. It's just a bit up in the air in terms of what fixtures we've got and when they play."
United withdrew from the FA Cup in October as they were isolating, although rules appear to be different in the Trophy.
While clubs such as Chasetown, Scarborough Athletic, Bedford and Canvey Island have all pulled out of the competition this season due to coronavirus, Maidstone United's round two contest against Poole was put back four days so it could take place when the Stones came out of isolation.
"These are the bits that have frustrated me this season, you see all kinds of inconsistencies from lots of clubs," Elliot added.
"And with us being Boston we'll end up having to play the game, I'm sure about that."
If the Pilgrims' contest against Chesterfield was put back then it would be likely that January 19's league fixture against Spennymoor Town would be re-arranged.
