The FA membership committee has advised against Hull City changing its name to Hull Tigers, putting the proposal in serious doubt.
Hull's owners, the Allam family, formally applied to alter the moniker in December after club chairman Assem Allam branded the City suffix "lousy" and "common".
The move has been met with derision from sections of the club's fans - who set up a campaign group named 'City Till We Die' to rally against the change - though Allam has claimed the switch would help Hull become financially self-sufficient.
Egyptian-born Allam, who made his fortune in marine generators after moving to Hull in the 1960s, has previously said he will happily sell the club if his proposal is rejected.
And that vow looks likely to be tested with the membership committee recommending that the FA council throw out any attempted change when they rule on the matter on April 9 - three days before Hull competes in its first FA Cup semifinal in 84 years against Sheffield United at Wembley.
An FA statement read: "Hull City are able to make a further submission to The FA Council in view of the written reasons, which they have received, before the 9 April meeting. A final decision will be made at that meeting."
Hull confirmed last week that it will ballot season ticket holders on their opinions over the name change.
The results could form a basis of the club's attempts to convince the FA council to go against its membership committee's recommendation.
Despite the off-field tension, Steve Bruce's side currently sits five points clear of the Premier League relegation zone with nine games to play this season.
