Nurmagomedov had been due to defend his lightweight title at UFC 249 this month but has now admitted defeat in his bid to keep the fight alive
The Barclays Center in New York was set to stage the event on April 18, despite the city being one of the areas worst-affected by the Covid-19 virus in the United States.
However the New York State Athletic Commission have since prohibited the venue from hosting the event, with a new location still to be confirmed.
Khabib Nurmagomedov was due to defend his UFC lightweight title against Tony Ferguson but has been forced to pull out due to him being stuck in lockdown in his native Russia.
Nevertheless White has insisted UFC 249 go ahead, earning him the sharp end of Arum’s tongue in response.
