The Premier League has not "worked through the consequences" if Chelsea are not sold by 31 May but believes the club will complete this season.
The comments were made at a Digital, Culture, Media and Sport session about the role of Russian money in clubs.
Chelsea are operating under a special licence after owner Roman Abramovich was sanctioned by the UK government.
"This is an extraordinary, complex and unprecedented situation," said Premier League policy chief Helen MacNamara.
"It is pretty new to all of us."
Russian Abramovich put the club up for sale but that process was halted after he had his British assets - including Chelsea - frozen as part of the UK government's response to his country's invasion of Ukraine.
