Hibernian manager John Collins is set to drop skipper Kevin Thomson and Scott Brown for the Boxing Day derby against Hearts, according to the players' agent Willie McKay.
The disgruntled duo sought a meeting with Collins after it emerged that the Easter Road club had turned down a £3million joint bid from Charlton.
McKay, who is looking for the Leith club to re-negotiate contracts signed by Brown and Thomson in March, told the Daily Record that the Hibernian boss reacted angrily to the players' request.
Hibernian take on St Mirren at home today, but the Leith club could be without two of their best players for the derby game at Tynecastle on Tuesday.
McKay said: 'Kevin and Scott asked to see the manager to discuss the Charlton offer.
'They wanted to ask why he did not inform them of the bid or give them any reason for it being rejected.
'John Collins reacted very angrily to this request, which took the players by surprise.
'He did more than threaten them - he told them they won't be playing against Hearts.
'That has devastated them because despite everything, they have the good of the club at heart.
'In fact, as we've said before, they'd be delighted to stay at Hibs and willing to take half the wages they could expect elsewhere to enable the club to make that happen.
'But Hibs have made it clear they won't discuss new deals while saying £3million is not an acceptable sum for them.
'You can understand then the boys' frustration and that will only intensify if the club continue to treat them in this manner.
'To threaten them with their places in the derby match is just the final straw.'
