Sheffield United have claimed they have accepted a bid from Hull for defender Harry Maguire -- but the Tigers were unaware of the news.
The League One club revealed they have "reluctantly" accepted the Tigers' offer after they met their valuation of the centre-back and he and his representatives were set to open talks over a move to the KC Stadium.
The Blades' managing director Mal Brannigan told the club's official website: "We made it clear that we wanted Harry to stay by offering him a new contract at the end of last season, unfortunately he and his representatives chose a different path.
"However, as he is under contract at Bramall Lane, we exercised our right to set our own valuation of him and after numerous bids which did not meet our expectations, Hull City increased their offer and we have reluctantly accepted.
"As we have previously stated, Sheffield United are not under pressure to sell our players but on this occasion it was deemed the best for all parties and now we move on with the aim of assisting Nigel Clough to strengthen his squad."
However, Hull subsequently released a statement on their official website saying they have not made a new offer.
It read: "Sheffield United rejected an offer from the club five days ago [Wednesday] for defender Harry Maguire. This was the club's final offer and we have since entered into discussions with other transfer targets.
"In light of Sheffield United's statement this morning the board will meet with manager Steve Bruce this afternoon to determine whether we now wish to pursue the transfer after the South Yorkshire club's apparent U-turn."
