The boxing heavyweight rematch between Dillian Whyte and Alexander Povetkin will now take place on March 27 in Gibraltar.
The bout was originally fixed for March.
But COVID-19 travel restrictions has seen the fight pushed back three weeks.
Boxing promoter, Eddie Hearn, said: “In the current environment we are always having to think on our feet,” said Hearn.
“We did everything to try and make March 6 happen but with the new travel restrictions, it was impossible.
“Now we have something outside the box, compelling and a unique setting for one of the heavyweight fights of the year – roll on the Rumble on the Rock!”
Whyte is attempting to avenge his shock knockout defeat last summer.
