Hearts could be on the verge of losing another player with Ryan Stevenson understood to have made himself unavailable for the Christmas Eve clash with Motherwell.
Stevenson held talks with manager Paulo Sergio where he expressed his frustration at recent delays to wage payments. The 27-year-old, whose contract expires at the end of the season, is believed to have decided to take several days off to consider his position.
The former Ayr midfielder, who was called up to the Scotland squad for last month`s friendly against Cyprus, has been linked with a move to Bristol City and could seek to leave under breach of contract next month.
Hearts have agreed to sell Iceland international Eggert Jonsson to Wolves on January 1 while Andrew Driver handed in a transfer request days earlier amid frustration over the financial situation and his lack of first-team chances.
Striker Calum Elliot and back-up goalkeeper Janos Balogh secured their departures in recent weeks while midfielder Rudi Skacel is out of contract in January.
The first-team squad are still awaiting their wages for December, which were due last week, after suffering major delays in their previous two monthly payments.
A Scottish Premier League sub-committee will rule on the issue on January 4 after considering a complaint from PFA Scotland on behalf of the players.
Meanwhile, Hearts have averted a winding-up order after settling a tax bill. The club confirmed the bill had been paid in full after Her Majesty`s Revenue and Customs lodged a petition for a winding-up order in the Court of Session last week.
The bill is reported to be a high six-figure sum and is not related to previous cases. Hearts confirmed they had paid a tax bill in August after being threatened with administration and a winding-up order was dismissed in early November.
The club stated on November 16 they had paid a tax bill of more than £1 million, which was one of the reasons given for problems in paying wages.
