The owners of Major League Baseball team the Chicago Cubs, the Ricketts family, have confirmed they are leading a group of investors which will make a bid for Chelsea on Friday.
The Ricketts have had a majority interest in the Cubs since 2009.
BBC Sport understands the group bid also includes US hedge fund entrepreneur Ken Griffin.
Roman Abramovich's attempt to sell the club has been halted after he was sanctioned by the UK government.
That move came in the wake of Russia's invasion of Ukraine, with Ambramovich understood to have strong ties to Russian President Vladimir Putin,
A statement from the Ricketts on Wednesday said they would share further details "in due course".
