Hull are understood to have launched a £5million move for Cardiff goalkeeper David Marshall.
Tigers caretaker boss Mike Phelan has stressed at regular intervals the club must strengthen before the transfer window closes since stepping in following Steve Bruce’s resignation, and the BBC claim they have now submitted a concrete bid for Marshall.
The Bluebirds have themselves signed shot-stopper Ben Amos from League One outfit Bolton Wanderers on Friday in a deal which could potentially pave the way for Marshall’s exit.
However, former number two Simon Moore did join Sheffield United last week and if Marshall were to be sold it would leave the Welsh club with just Amos and Ben Wilson as options in goal, with the latter having managed just eight Football League appearances during a loan stint at AFC Wimbledon.
Marshall, 31, could be involved for Cardiff against Reading on Saturday despite the bid from the Tigers.
