Bolton and Bury's opening League One games are "likely" to be suspended if they do not meet a new English Football League deadline to provide evidence of their financial viability, reports BBC Sport.
Both clubs have until 17:00 BST on Monday to show they can meet "all outstanding commitments".
Bolton have been in administration since 13 May, with a protracted takeover still not complete.
Bury, meanwhile, need to give details of how they plan to settle their debts after a company voluntary arrangement (CVA) was approved by creditors on 18 July.
Both will start the 2019-20 campaign with 12-point deductions resulting from their financial difficulties.
