Bolton players are reportedly refusing to train until wages are paid for March.
Staff have not been paid on time for a second month in a row, as uncertainty continues to cloud the Sky Bet Championship club.
Bolton have declined to comment.
On Wednesday, the High Court will hear a winding-up petition issued by HMRC over an unpaid tax bill of £1.2million, having adjourned the case on March 20.
Bolton had told the High Court they were in the process of selling the club but no deal has been finalised, leaving staff facing late payment once again.
Players have been angered by the lack of information regarding a potential takeover or Wednesday's hearing, leading them to take action on behalf of all club staff.
Wanderers still face the threat of liquidation or administration, but the adjournment means they have avoided a 12-point deduction this season.
