Both men suffer from dwarfism and have so far been unable to agree terms and the fight has been put on the backburner.
The 18-year-olds were even filmed together earlier this year as they appeared to bond over a dove.
Hasbulla was in Abu Dhabi to support Islam Mackachev who submitted Dan Hooker in the first round to cement his lightweight title claims.
Rozik had attached himself to Hooker's camp as the social media stars stole the limelight in the desert.
Hasbulla was photographed sitting next to UFC president Dana White before being carried into the octagon following Mackachev's victory.
He also posed with Nurmagomedov who has turned his attention to coaching since he retired from competing last year.
Hasbulla stands at around one metre tall and weighs around 16kg. His condition is known as Growth Hormome Deficiency which affects the pituitary gland which is responsible for producing hormones.
His fight with Rozik appeared to be back on when a mystery sponsor agreed to stump up the $200,000 purse Hasbulla was demanding - but no date has been set.
