According to The Athletic, who have broken the story, 49ers Enterprise will not be able to complete a purported £475m purchase if Radrizanni’s company Aser were to buy another club before the deadline.
However, the report continues that a buy-out might actually happen sooner.
The deal also includes the purchase of Elland Road, which Radrizanni bought for £20m upon his 2017 acquisition.
The club’s famous stadium had been out of its control since 2004.
