Tyson Fury is expected to face Anthony Joshua in a blockbuster heavyweight clash later this year.
What's the latest development?
The fight can take place at Wembley Stadium if local authorities agree to stage the fight at a later time than usual.
Turki Alalshikh, the organiser of the all-British bout, wants the fight to start at a time that works for a global audience.
Why the late start time?
Alalshikh intends to hold talks with London Mayor Sir Sadiq Khan to obtain permission to host a late-night fight in the capital.
Given main events at UK bouts tend to start between 10pm and 11pm, Alalshikh would appear to be suggesting the much-anticipated matchup would start after midnight.
What's next for Tyson Fury?
Tyson Fury faces Mariusz Wach in Thailand on July 24, while Anthony Joshua takes on Kristian Prenga a day later in Saudi Arabia.
Both former world champions are competing in warm-up fights later in July, with a surprise defeat or injury for either appearing to be the only potential obstacles to their meeting going ahead, most likely in November.
What does Alalshikh say?
Alalshikh said: "I tell you from the beginning, it depends if England give us all that we need, we want the fight here in England.
But we want the time zone of all the world, especially in America. If they allowed us to have Wembley late in the night, we want to do it in England. It is about the time and viewership.
Alalshikh will talk with the mayors and Prince Abdullah bin Khaled bin Sultan to make the fight happen at Wembley Stadium.
