Bolton have had a third pre-season fixture called off after Saturday's match with Oldham Athletic was postponed.
Wanderers, relegated to Sky Bet League One after they finished second-bottom of the Championship last season, have already had matches with National League North side Chester and Championship side Preston cancelled.
Their opening friendly was called off after players refused to play due to an ongoing dispute over unpaid wages and Sky Sports News understands they remain unwilling to take part in matches.
In a statement released on Monday afternoon, Oldham said: "The club have made the decision to find another opponent for Saturday's game due to the doubt of the original fixture going ahead."
Bolton are due to begin their league campaign away to Wycombe on August 3, although PFA chief executive Gordon Taylor has voiced concerns the club may not be able to fulfil their fixtures this season.
Members of the Bolton squad claim they and the club's coaching staff had not been paid for 20 weeks, while they found their training facilities locked up when they returned for pre-season training.
