Bolton's players and staff have not been paid February's wages on time, Press Association Sport understands.
The embattled Sky Bet Championship club announced on Sunday that an agreement in principle had been reached for chairman Ken Anderson to sell his shares in the club.
Due diligence into the sale of Anderson's Inner Circle Investments' total shareholding in Burnden Leisure is under way as a difficult chapter edges closer to a conclusion.
Bolton have been beset with financial difficulties this season and Press Association Sport understands employees have been informed that February's wages would be late.
The club have yet to make an official comment on this latest issue.
Bolton languish 23rd in the Championship and sit four points from safety ahead of Saturday's trip to Swansea.
The consortium looking to take over the club is reportedly led by businessman Parminder Basran, who is founder and managing partner of investment firm VGC Partners.
