Promoter Eddie Hearn has admitted Anthony Joshua's next world heavyweight title defence against Kubrat Pulev could be pushed back a month to July.
Joshua is scheduled to face the Bulgarian at Tottenham's new stadium on 20 June, but that date could now be required by the club for a potential extension of the Premier League campaign.
Hearn, whose Matchroom organisation earlier confirmed the postponement of all boxing events in March and April, once again dismissed the prospect of any of his major bouts being staged behind closed doors.
Referring to the 20 June date, Hearn told Sky Sports News: "At the moment it's still in place.
"Obviously with the news of the Euros being cancelled (Euro 2020 has been postponed until next year) and the possible extension of the Premier League season, Spurs may need that stadium in June.
"We do have an option to run that fight in July as well at the same stadium. Everything now is really a case-by-case situation and a day-by-day situation of trying to think on your feet.
"June 20 is a long time away, it's still in our plans and we have been speaking to Tottenham to make sure we're all on the same page and that we know we have the same strategy moving forward."
Prior to Joshua's bout with Pulev, Dillian Whyte is scheduled to meet Alexander Povetkin on 2 May and Dereck Chisora is set to face Oleksandr Usyk on 23 May - both bouts which Hearn says are "subject to change".
