Anthony Joshua's world heavyweight title fight against Kubrat Pulev on 20 June could be moved to July, says promoter Eddie Hearn.
The 30-year-old Briton is due to defend his WBA, WBO and IBF belts at the Tottenham Hotspur Stadium.
"We do have a potential date in July but, right now, we are hoping June 20 can remain the date," Matchroom Boxing's Hearn told Sky Sports.
Bulgarian Pulev, 38, is the mandatory IBF challenger to take on Joshua.
With the uncertainty around when the remaining games in domestic football will be completed because of the coronavirus outbreak, and the possibility the season could extend into the summer months, Hearn said he has had conversations with Tottenham to "make sure we're all on the same page".
"We know we have the same strategy moving forward," added Hearn. "Obviously the Premier League decision will play a big part in a number of sports. Plans to put new dates in place and that fight as well."
Joshua won the WBA, WBO and IBF belts back with a unanimous points victory over Andy Ruiz Jr last December.
If the fight with Pulev does go ahead, it will be Joshua's first bout in the United Kingdom since beating Alexander Povetkin at Wembley in September 2018.
He was initially due to fight Pulev at Cardiff's Principality Stadium in October 2017 but the Bulgarian withdrew after suffering a shoulder injury in sparring, with Carlos Takam stepping in to replace him at 12 days' notice.
