Dillian Whyte’s rematch with Alexander Povetkin has been postponed to Saturday, March 27 and will now take place in Gibraltar.
Whyte suffered a shock defeat to Povetkin back in August and has been seeking revenge.
The heavyweights were due to clash in November but the Russian was hospitalised with coronavirus.
Their second clash was then supposed to usher in the new year of boxing but, at the start of January, the sport was suspended amid the growing coronavirus cases in the UK.
A new date of March 6 had been set, and was supposed to take place at Wembley Arena, but it has again been moved, this time due to travel restrictions due to the COVID-19 pandemic.
It has been pushed back three weeks and will take place in Gibraltar.
Matchroom Sport managing director Eddie Hearn said: “In the current environment we are always having to think on our feet. 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!”
