Skysports.com understands Leicester's play-off preparations were rocked by a row involving several members of the squad.
A heated row is believed to have occured last Friday just 48 hours before the first leg of the play-off defeat to Cardiff.
The argument was sparked over an inappropriate comment made by one of the Foxes players to his team-mates.
It is believed Foxes boss Nigel Pearson was made aware of the row and he held a meeting to discuss the incident with those involved on the Saturday before the Cardiff game.
Leicester went on to lose the first leg 1-0 on Sunday before going out on Wednesday on penalties after a dramatic second leg in Cardiff.
Leicester have so far refused to comment on the rumours and it remains to be seen if they will take any action against the players involved in the incident.
Apparently Wayne Brown voted BNP in the election and let it slip in training, with Lloyd Dyer and James Vaughan taking offence.
